Lucas, Sebastian; Kammerer, Jochen; Pfannmoeller, Martin; Schroeder, Rasmus R.; He, Yakun; Li, Ning; Brabec, Christoph J.; Leydecker, Tim; Samori, Paolo; Marszalek, Tomasz; Pisula, Wojchiech; Mena-Osteritz, Elena; Baeuerle, Peter published their research in Solar RRL in 2021. The article was titled 《Molecular Donor-Acceptor Dyads for Efficient Single-Material Organic Solar Cellsã€?Application of 4048-33-3 The article contains the following contents:

Single-material organic solar cells (SMOSCs) promise several advantages with respect to prospective applications in printed large-area solar foils. Only one photoactive material has to be processed and the impressive thermal and photochem. long-term stability of the devices is achieved. Herein, a novel structural design of oligomeric donor-acceptor (D-A) dyads 1-3 is established, in which an oligothiophene donor and fullerene acceptor are covalently linked by a flexible spacer of variable length. Favorable optoelectronic, charge transport, and self-organization properties of the D-A dyads are the basis for reaching power conversion efficiencies up to 4.26% in SMOSCs. The dependence of photovoltaic and charge transport parameters in these ambipolar semiconductors on the specific mol. structure is investigated before and after post-treatment by solvent vapor annealing. The inner nanomorphol. of the photoactive films of the dyads is analyzed with transmission electron microscopy (TEM) and grazing-incidence wide-angle X-ray scattering (GIWAXS). Combined theor. calculations result in a lamellar supramol. order of the dyads with a D-A phase separation smaller than 2 nm. The mol. design and the precise distance between donor and acceptor moieties ensure the fundamental phys. processes operative in organic solar cells and provide stabilization of D-A interfaces. The experimental part of the paper was very detailed, including the reaction process of 6-Aminohexan-1-ol(cas: 4048-33-3Application of 4048-33-3)

《Interplay of Porosity, Wettability, and Redox Activity as Determining Factors for Lithium-Organic Electrochemical Energy Storage Using Biomoleculesã€?was written by Ilic, Ivan K.; Perovic, Milena; Liedel, Clemens. Application In Synthesis of 3,5-Dihydroxybenzaldehyde And the article was included in ChemSusChem in 2020. The article conveys some information:

Although several recent publications describe cathodes for electrochem. energy storage materials made from regrown biomass in aqueous electrolytes, their transfer to lithium-organic batteries is challenging. To gain a deeper understanding, we investigate the influences on charge storage in model systems based on biomass-derived, redox-active compounds and comparable structures. Hybrid materials from these model polymers and porous carbon are compared to determine precisely the causes of exceptional capacity in lithium-organic systems. Besides redox activity, particularly, wettability influences capacity of the composites greatly. Furthermore, in addition to biomass-derived mols. with catechol functionalities, which are described commonly as redox-active species in lithium-bio-organic systems, we further describe guaiacol groups as a promising alternative for the first time and compare the performance of the resp. compounds In the part of experimental materials, we found many familiar compounds, such as 3,5-Dihydroxybenzaldehyde(cas: 26153-38-8Application In Synthesis of 3,5-Dihydroxybenzaldehyde)

In 2013,Biodegradation included an article by Ogata, Yuka; Toyama, Tadashi; Yu, Ning; Wang, Xuan; Sei, Kazunari; Ike, Michihiko. Application In Synthesis of 4-Butylbenzene-1,2-diol. The article was titled 《Occurrence of 4-tert-butylphenol (4-t-BP) biodegradation in an aquatic sample caused by the presence of Spirodela polyrrhiza and isolation of a 4-t-BP-utilizing bacteriumã€? The information in the text is summarized as follows:

Although 4-tert-butylphenol (4-t-BP) is a serious aquatic pollutant, its biodegradation in aquatic environments has not been well documented. In this study, 4-t-BP was obviously and repeatedly removed from water from four different environments in the presence of Spirodela polyrrhiza, giant duckweed, but 4-t-BP persisted in the environmental waters in the absence of S. polyrrhiza. Also, 4-t-BP was not removed from autoclaved pond water with sterilized S. polyrrhiza. These results suggest that the 4-t-BP removal from the environmental waters was caused by biodegradation stimulated by the presence of S. polyrrhiza rather than by uptake by the plant. Moreover, Sphingobium fuliginis OMI capable of utilizing 4-t-BP as a sole carbon and energy source was isolated from the S. polyrrhiza rhizosphere. Strain OMI degraded 4-t-BP via a meta-cleavage pathway, and also degraded a broad range of alkylphenols with linear or branched alkyl side chains containing two to nine carbon atoms. Root exudates of S. polyrrhiza stimulated 4-t-BP degradation and cell growth of strain OMI. Thus, the stimulating effects of S. polyrrhiza root exudates on 4-t-BP-degrading bacteria might have contributed to 4-t-BP removal in the environmental waters with S. polyrrhiza. These results demonstrate that the S. polyrrhiza-bacteria association may be applicable to the removal of highly persistent 4-t-BP from wastewaters or polluted aquatic environments. The experimental process involved the reaction of 4-Butylbenzene-1,2-diol(cas: 2525-05-5Application In Synthesis of 4-Butylbenzene-1,2-diol)

4-Butylbenzene-1,2-diol(cas: 2525-05-5) belongs to organoboron compounds.

Didier, Eric; Loubinoux, Bernard; Ramos Tombo, Gerardo M.; Rihs, Grety published an article in Tetrahedron. The title of the article was 《Chemo-enzymatic synthesis of 1,2- and 1,3-amino alcohols and their use in the enantioselective reduction of acetophenone and anti-acetophenone oxime methyl ether with boraneã€?Related Products of 135969-66-3 The author mentioned the following in the article:

New chiral amino alcs. were enantioselectively synthesized using biotransformations as the key steps. Thus, the Bakers yeast reduction of the β-keto ester I gave hydroxy ester II (R = CO2Et) in 34% yield with high enantio- and diastereoselectivity. Saponification of the ester gave acid II (R = CO2H), which was converted to oxazolidinone III by a modified reaction with diphenylphosphorazide. Hydrolysis of III with KOH gave amino alc. II (R = NH2). The new chiral amino alcs. were used as ligand in the enantioselective borane reduction of acetophenone and of the corresponding anti-oxime Me ether.
