Application of 627-18-9In 2020 ,《Metathesis cyclopolymerization triggered self-assembly of azobenzene-containing nanostructure》 appeared in Molecules. The author of the article were Song, Wei; Shen, Jiamin; Li, Xiang; Huang, Jinhui; Ding, Liang; Wu, Jianhua. The article conveys some information:
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. After reading the article, we found that the author used 3-Bromopropan-1-ol(cas: 627-18-9Application of 627-18-9)
3-Bromopropan-1-ol(cas: 627-18-9) is used in the synthesis of fluorescent halide-sensitive quinolinium dyes, chiral, quaternary prolines through cyclization of quaternary amino acids and molten salt-polymers. It is utilized for the study of micellar media and in microemulsions based on cationic or a nonionic surfactant by reacting with phenols.Application of 627-18-9
