《Protonation-Triggered Supramolecular Gel from Macrocyclic Diacetylene: Gelation Behavior, Topochemical Polymerization, and Colorimetric Response》 was written by Shin, Geon; Khazi, Mohammed Iqbal; Kim, Jong-Man. Name: 3,5-Dihydroxybenzaldehyde And the article was included in Langmuir in 2020. The article conveys some information:

Herein, a novel supramol. gel was fabricated through the protonation-triggered unidirectional self-assembly of pyridine-attached macrocyclic diacetylene (PyMCDA). Basic nitrogen of a pyridine ring with a strong affinity toward proton transforms the neutral PyMCDA into gelator in its protonated pyridinium salt form (PyMCDA-H+), which further evolves to nano-fibrillar networks to yield a supramol. gel. Under the irradiation of UV light, the white color gel turned to a robust covalently cross-linked blue-phase PDA gel. Interestingly, polymeric PyMCPDA-H+ gel exhibits a naked-eye detectable reversible blue-red colorimetric response for alternating acid/base (H2SO4/NH4OH) and colorimetric sensitivity toward selected anions: CH3COO-, CN-, HCOO-, and CH3CH2COO-. It is with the hope that this work point toward the utility and versatility of macrocyclic PDAs for constructing chromogenic supramol. gels for their possible use in sensing systems. In addition to this study using 3,5-Dihydroxybenzaldehyde, there are many other studies that have used 3,5-Dihydroxybenzaldehyde(cas: 26153-38-8Name: 3,5-Dihydroxybenzaldehyde) was used in this study.

The author of 《Flexible aromatic disulfide monomers for high-performance self-healable linear and cross-linked poly(urethane-urea) coatings》 were Nevejans, Sil; Ballard, Nicholas; Fernandez, Mercedes; Reck, Bernd; Asua, Jose M.. And the article was published in Polymer in 2019. Related Products of 627-18-9 The author mentioned the following in the article:

Implementation of the self-healing concept in coatings is challenging because they have to combine mech. strength and chain mobility. This challenge is addressed in this work by studying the effect of the polymer microstructure on the mech. properties and self-healing ability of waterborne poly(urethane-urea) coatings containing aromatic disulfide dynamic bonds. The structural modifications studied are the concentration and flexibility of the aromatic disulfide units and the effect of crosslinking. The effects and limits of these structural changes on the mech. properties of the polymers and their healability were determined via a combination of DMA measurements, tensile tests, and rheol. and scratch closure experiments It was found that the flexibility of the disulfide unit was key to develop more efficient self-healing materials which offer the necessary mol. mobility for self-healing while simultaneously maintaining a level of mech. strength that are essential for coating applications. In the experiment, the researchers used 3-Bromopropan-1-ol(cas: 627-18-9Related Products of 627-18-9)

In 2019,Synlett included an article by Miura, Tomoya; Moriyama, Daisuke; Funakoshi, Yuuta; Murakami, Masahiro. Computed Properties of C6H12O. The article was titled 《Photoinduced 1,2-Hydro(cyanomethylation) of Alkenes with a Cyanomethylphosphonium Ylide》. The information in the text is summarized as follows:

An efficient method was developed for the 1,2-hydro(cyanomethylation) of alkenes, in which a cyanomethyl radical species was generated from a cyanomethylphosphonium ylide by irradiation with visible light in the presence of an iridium complex, a thiol, and ascorbic acid. The cyanomethyl radical species then adds across the C:C double bond of an alkene to form an elongated alkyl radical species that accepts a hydrogen atom from the thiol to produce an elongated aliphatic nitrile. The ascorbic acid acts as the reductant to complete the catalytic cycle. In the experimental materials used by the author, we found 5-Hexen-1-ol(cas: 821-41-0Computed Properties of C6H12O)

The author of 《Transition potentials of some triphenylmethane dyes redox indicators》 were Belcher, R.; Brazier, J. N.; Stephen, W. I.. And the article was published in Talanta in 1965. Synthetic Route of C10H14O2 The author mentioned the following in the article:

The transition ranges of 3 triphenylmethane dye redox indicators have been redetermined The figures found in 1F H2SO4 are appreciably higher than earlier values; the new figures are more in accord with the behavior of these indicators when compared with 2,2′-dipyridyl and substituted ferroins. At high acidities the indicators function in the dichromate-Fe(II) system. In a HClO4 medium the figures are significantly higher and fall into a range which accounts for the fact that all 3 dyes function as indicators with hexaperchloratocerate(IV) titrant. The potentials of ferroin and is derivatives are apparently unaffected by change of medium. The experimental process involved the reaction of 4-Butylbenzene-1,2-diol(cas: 2525-05-5Synthetic Route of C10H14O2)

4-Butylbenzene-1,2-diol(cas: 2525-05-5) belongs to organoboron compounds. Organoboron compounds are versatile intermediates and as such are some of the most important classes of reagents in modern organic chemistry. Organoboron compounds are less toxic than organostannane reagents, and unlike alkynylzinc and magnesium, many organoboron compounds possess remarkable oxidative and thermal stabilities.

Electric Literature of C7H7BrOIn 2019 ,《Efficient Synthesis of Quinazolinones by Transition-Metal-Free Direct Aerobic Oxidative Cascade Annulation of Alcohols with o-Aminoarylnitriles》 appeared in ChemSusChem. The author of the article were Wang, Qi; Lv, Miao; Liu, Jianping; Li, Yang; Xu, Qing; Zhang, Xu; Cao, Hongen. The article conveys some information:

A mild and atom-economic method was developed for direct and efficient synthesis of quinazolinones I (R1 = H, 5-Cl, 6-Br, 7-CH3, etc.; R2 = C6H5, naphthalen-2-yl, thiophen-2-yl, etc.) through a transition-metal-free aerobic oxidative cascade annulation reaction of widely available o-aminoarylnitriles R32-H2NC6H3CN (R3 = H, 4-CH3, 5-Br, 6-Cl, etc.) and alcs. R2CH2OH. Air could be employed as an effective oxidant under mild conditions, generating water as the only byproduct. Possibly owing to the ”cesium effect”, the water-soluble base CsOH was found to be crucial in all key steps of the reaction mechanism. Because a wide range of substrates can be used to prepare substituted quinazolinones without contamination by transition-metal residues, this method may be of interest for application in pharmaceutical synthesis. Possible reaction paths were also proposed according to control reactions. In the experiment, the researchers used many compounds, for example, (4-Bromophenyl)methanol(cas: 873-75-6Electric Literature of C7H7BrO)

Azobenzene (AB) units were successfully introduced into poly(1,6-heptadiyne)s in order to ensure smooth synthesis of double- and single-stranded poly(1,6-heptadiyne)s (P1 and P2) and simultaneously realize the self-assembly by Grubbs-III catalyst-mediated metathesis cyclopolymn. (CP) of AB-functionalized bis(1,6-heptadiyne) and 1,6-heptadiyne monomers (M1 and M2). Monomers and polymers were characterized by 1H NMR, mass spectroscopy, and GPC techniques. The double-stranded poly(1,6-heptadiyne)s exhibited a large scale of ordered ladder nanostructure. This result was attributed to the π-π attractions between end groups along the longitudinal axis of the polymers and van der Waals interactions between the neighboring polymeric backbones. While the azo chromophore connected in the side chain of P2 induced conformation of micelles nanostructure during the CP process without any post-treatment. Furthermore, the photoisomerization of azo units had an obviously different regulatory effect on the conjugated degree of the polymer backbone, especially for the single-stranded P2, which was attributed to the structural differences and the interaction between AB chromophores in the polymers.
