Extraordinary magnetic field effects on the LC phases of homochiral and racemic 4-cyanoresorcinol-based diamagnetic bent-core mesogens was written by Ocak, Hale;Bilgin Eran, Belkiz;Nuray, Sevgi;Ozkonstanyan, Aykun;Poppe, Silvio;Tschierske, Carsten. And the article was included in Journal of Materials Chemistry in 2021.Name: 3,7-Dimethyloctan-1-ol The following contents are mentioned in the article:

4-Cyanoresorcinol based bent-core compounds combining one branched chiral with one achiral linear end-chain have been synthesized in enatiomerically pure and one compound also in racemic form. All homochiral compounds form a chiral cybotactic nematic phase at relatively low temperature with a selective reflection ranging from the near IR to near UV. For the compound with the longest chains superparaelec. and antiferroelec. switching smectic phases were observed, whereas the corresponding racemate is non-polar. This is attributed to sterically induced polarization by the denser packing of uniform enantiomers due to chirality synchronization of the helical conformers. For the racemic mixture this chirality synchronization requires addnl. surface stabilization. There are unprecedented effects of an applied magnetic field (1 T) on the LC phases, leading to a layer shrinkage by 6-13% for the enantiomer and a layer expansion by 5-8% for the racemate. It is proposed that the magnetic field couples with the π-systems of the almost rod-like mols. For the racemate this increases the core order, whereas for the enantiomer the reduction of the heliconical twist is considered to provide the major effect. These magnetic field effects could lead to new applications of chiral LC materials at the cross-over between rod-like and bent shapes. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Name: 3,7-Dimethyloctan-1-ol).

Novel phenazine fused triphenylene discotic liquid crystals: synthesis, characterisation, thermal, optical and nonlinear optical properties was written by Gowda, Ashwathanarayana;Jacob, Litwin;Joy, Nithin;Philip, Reji;Kumar, Sandeep. And the article was included in New Journal of Chemistry in 2018.Product Details of 106-21-8 The following contents are mentioned in the article:

A straightforward synthesis of novel phenazine fused triphenylene discotic liquid crystals (DLCs) is realized. The condensation of 3,4-diaminobenzoic acid with a triphenylene-1,2-diquinone intermediate gives an acid derivative which upon esterification with aliphatic alcs. produces the corresponding monomeric ester derivatives of the phenazine fused triphenylene discotic liquid crystals. The intermediate acid derivative exhibits a rectangular columnar phase along with a high isotropic phase transition temperature However, the monomeric ester derivatives show a hexagonal columnar mesophase over a broad temperature range and stable when decreased to room temperature upon cooling from the isotropic phase. The mesomorphic properties of the acid and monomeric ester derivatives of the phenazine fused triphenylene DLCs were characterized by polarized optical microscopy (POM), DSC and x-ray diffraction studies (XRD). The mol. structures of the intermediate and final compounds were characterized by spectral and elemental anal. The photophys. properties of all the monomeric ester compounds were studied in an anhydrous chloroform solvent and absorption bands around 291-472 nm and the corresponding emission bands at 658-661 nm were observed, resp. The π-extended conjugation in these materials gives rise to high nonlinear optical properties. These materials have immense potential for use in electrooptical applications.

Synthesis of menthol from citronellal over supported Ru- and Pt-catalysts in continuous flow was written by Azkaar, Muhammad;Maki-Arvela, Paivi;Vajglova, Zuzana;Fedorov, Vyacheslav;Kumar, Narendra;Hupa, Leena;Hemming, Jarl;Peurla, Markus;Aho, Atte;Murzin, Dmitry Yu. And the article was included in Reaction Chemistry & Engineering in 2019.Quality Control of 3,7-Dimethyloctan-1-ol The following contents are mentioned in the article:

One-pot menthol synthesis from citronellal in a trickle bed reactor was investigated using Ru/H-beta-300 zeolite extrudates without any binder and Pt- and Ru-extrudates containing 70 wt% H-beta-25 zeolites and 30 wt% bentonite binder using different methods of metal loading on the extrudates. The catalytic results were correlated with the physico-chem. properties of bifunctional zeolite-based extrudates. The conversion of citronellal to menthol was nearly the same for Pt extrudates being independent of catalyst acidity or the metal particle size. Ru extrudates also exhibited similar conversion levels as a function of time-onstream, except for very mildly acidic Ru/beta-300 extrudates, which gave much lower conversion. Pt extrudates showed better stability with time on stream in comparison with Ru extrudates. The best catalyst giving the highest menthol yield and a low amount of acyclic hydrogenation products was Ru-beta-bentonite extrudates where Ru was located randomly in the mixture of 70% H-beta-25 and 30% bentonite binder. Hydrogenation was more prominent for Pt than for Ru catalysts, most probably due to their higher hydrogenation ability. Stereoselectivity to menthol varied in the trickle bed reactor in the range of 67 to 73%. In a batch reactor for Ru- and Pt-catalysts independent of support acidity, it was in the range of 70-71%. The reuse of Ru/H-beta-300 extrudates was successfully demonstrated.

And the article was included in Anti-Cancer Agents in Medicinal Chemistry in 2019.Product Details of 106-21-8 The following contents are mentioned in the article:

The DNA repair enzyme tyrosyl-DNA-phosphodiesterase 1 (TDP1) is a current inhibition target to improve the efficacy of cancer chemotherapy. Previous studies showed that compounds combining adamantane and monoterpenoid fragments are active against TDP1 enzyme. This investigation is focused on the synthesis of monoterpenoid derived esters of 1-adamantane carboxylic acid as TDP1 inhibitors. New esters were synthesized by the interaction between 1-adamantane carboxylic acid chloride and monoterpenoid alcs. The esters were tested against TDP1 and its binding to the enzyme was modeling. 13 Novel ester-based TDP1 inhibitors were synthesized with yields of 21-94%; of these, nine esters had not been previously described. A number of the esters were found to inhibit TDP1, with IC₅₀ values ranging from 0.86-4.08μM. Mol. modeling against the TDP1 crystal structure showed a good fit of the active esters in the catalytic pocket, explaining their potency. A non-toxic dose of ester, containing a 3,7-dimethyloctanol fragment, was found to enhance the cytotoxic effect of topotecan, a clin. used anti-cancer drug, against the human lung adenocarcinoma cell line A549. The esters synthesized were found to be active against TDP1 in the lower micromolar concentration range, with these findings being corroborated by mol. modeling. Simultaneous action of the ester synthesized from 3,7-dimethyloctanol-1 and topotecan revealed a synergistic effect. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Product Details of 106-21-8).

Self-Organization and Charge Transport Properties of Selenium and Tellurium Analogues of Polythiophene was written by Ye, Shuyang;Janasz, Lukasz;Zajaczkowski, Wojciech;Manion, Joseph G.;Mondal, Anirban;Marszalek, Tomasz;Andrienko, Denis;Muellen, Klaus;Pisula, Wojciech;Seferos, Dwight S.. And the article was included in Macromolecular Rapid Communications in 2019.Electric Literature of C10H22O The following contents are mentioned in the article:

A series of conjugated polymers comprising polythiophene, polyselenophene, and polytellurophene with branched 3,7-dimethyloctyl side chains, well-matched mol. weight, dispersity, and regioregularity is synthesized. The ionization potential is found to vary from 5.14 to 5.32 eV, with polytellurophene having the lowest potential. Field-effect transistors based on these materials exhibit distinct hole transport mobility that varies by nearly three orders of magnitude, with polytellurophene having the highest mobility (2.5 × 10^-2 cm² V^-1 s^-1). The large difference in mobility demonstrates the significant impact of heteroatom substitution. Although the series of polymers are very similar in structure, their solid-state properties are different. While the thin film microstructure of polythiophene and polyselenophene is identical, polytellurophene reveals globular features in the film topog. Polytellurophenes also appear to be the least crystalline, even though their charge transport properties are superior to other samples. The torsional barrier and degree of planarity between repeat units increase as one moves down group-16 elements. These studies show how a single atom in a polymer chain can have a substantial influence on the bulk properties of a material, and that heavy group-16 atoms have a pos. influence on charge transport properties when all other variables are kept unchanged.

Hydrogenation of Citral on Pt/SiO₂ Catalysts: Effect of Sn Addition and Type of Solvent was written by Barrales-Cortes, C. A.;Perez-Pastenes, H.;Pina-Victoria, J. C.;Viveros-Garcia, T.. And the article was included in Topics in Catalysis in 2020.Reference of 106-21-8 The following contents are mentioned in the article:

This work deals with the liquid-phase hydrogenation of citral over Pt monometallic and PtSn bimetallic catalysts supported on com. silica. Bimetallic catalysts contain different Sn/Pt molar ratio of 0.5, 1.0 and 1.5. Cyclohexane or 2-propanol were used as solvent. The catalysts were characterized by N₂-physisorption, XRD, NH₃-TPD, H₂-chemisorption, and TPR. Both XRD and TPR results showed the formation of PtSn and Pt₃Sn. The proportion of Pt-Sn alloys was related to the Sn/Pt molar ratio: the greater the Sn/Pt molar ratio, the greater the amount of PtSn alloy species. The amount of these species was related to the catalytic activity and selectivity in the hydrogenation of citral. Pt monometallic catalysts showed a high initial catalytic activity with high selectivity to citronellal. Bimetallic catalysts exhibited high activity and selectivity to unsaturated alcs. as geraniol and nerol. With cyclohexane as solvent, a greater amount of Pt₃Sn species promote consecutive hydrogenations, and with a greater amount of PtSn alloy the formation of compounds related to cyclization of citronellal was observed The results showed that using a balanced amount of species (Pt₃Sn and PtSn) and 2-propanol as solvent, a synergic effect that promotes high activity and selectivity to geraniol and nerol was observed maintaining the same levels of selectivity along reaction time. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Reference of 106-21-8).

Functionalized alkenyl side chains: a feasible strategy to improve charge transport and photovoltaic performance was written by Zheng, Bing;Liu, Juan;Pan, Xuexue;Zhang, Yu;Wang, Zaiyu;Liu, Feng;Wan, Meixiu;Huo, Lijun. And the article was included in Journal of Materials Chemistry in 2020.Application of 106-21-8 The following contents are mentioned in the article:

To pursue effective charge transport and high fill factor (FF) in photovoltaic devices, adopting ordered polymers with enhanced hole mobility is greatly desired. Currently, a popular strategy in improving charge transport has been applied by enforcing the coplanarity of fused-ring conjugated structures. However, their synthetic complexity hinders their further development. Here, an effective strategy is successfully developed to introduce soluble alkenyl side chains in D-A type photovoltaic polymer backbones to improve the charge transport ability and photovoltaic performance. The introduction of the trans-vinylene (CH=CH) linkage in alkenyl side chains strengthens the polymeric crystalline properties and charge transport ability, and further improves the photovoltaic performance. Meanwhile, a high FF of 0.73 can still be obtained for a device with a film thickness of 200 nm. The low cost, feasible chem. strategy could potentially be applied for other thickness-insensitive organic photovoltaic materials design. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Application of 106-21-8).

3,7-Dimethyloctan-1-ol (cas: 106-21-8) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group.

Headspace GC-MS (gas chromatog.-mass spectrometry) and peptide based gas sensor array (E-nose) anal. were performed to evaluate the volatile fraction of durum wheat pasta samples of different com. value and furosine content. A clear discrimination among high-price and low price samples of pasta was achieved using a simple PCA (Principal Component Anal.) of GC-MS dataset. This was attributed to the quality of semolina used in the process. Linear discriminant anal. (LDA) allowed discrimination among low or high furosine content in the samples. The peptide based e-nose was tested initially on a set of pure key volatiles found in GC-MS anal. and then on pasta samples. Discrimination of pasta samples having different com. value was achieved. This work demonstrates that volatiles can be used to determine the quality of pasta with respect to semolina and thermal treatment. Moreover, the peptide-based e-nose represents a useful tool alternative to GC-MS to detect off-flavours and quality of the semolina in pasta.

Protein hydrolysates of porcine hemoglobin and blood: Peptide characteristics in relation to taste attributes and formation of volatile compounds was written by Fu, Yu;Bak, Kathrine H.;Liu, Jing;De Gobba, Cristian;Toestesen, Marie;Hansen, Erik T.;Petersen, Mikael A.;Ruiz-Carrascal, Jorge;Bredie, Wender L.

The objective of this study was to investigate the impact of endo- and exo-peptidase treatment on certain structural characteristics of peptides and volatile compounds of porcine Hb and whole blood hydrolyzates. Porcine Hb and whole blood were hydrolyzed by endo- and exo-peptidases. The presence of exopeptidases reduced the bitterness and altered the volatile profiles of protein hydrolyzates. Exopeptidase treatment can release terminal amino acids from peptides, which in turn may contribute to formation of volatile compounds by Maillard reactions. In contrast, endopeptidases conferred a slightly bitter taste and different volatile profiles. For Hb hydrolyzates, principal component anal. revealed that proteases were categorized into three groups based on endo- or exo-peptidase activity. Whole blood is a more complex raw material, yet the proteases were still categorized in a similar fashion. This work contributes to understanding structural characteristics responsible for taste and volatile profiles of protein hydrolyzates.
