In 2022,Yamada, Shigeyuki; Yoshida, Keigo; Sakurai, Tsuneaki; Hara, Mitsuo; Konno, Tustome published an article in Molecular Systems Design & Engineering. The title of the article was 《Effect of fluorine atoms in flexible chains on the phase transitions and photophysical behavior of D-π-A-type 4-alkoxy-4′-cyanodiphenylacetylene》.Application of 623-00-7 The author mentioned the following in the article:
D-π-A-type 4-alkoxy-4′-cyanodiphenylacetylenes bearing a decyloxy chain show a nematic liquid crystalline (LC) phase, whereas the incorporation of a semifluoroalkyl fragment results in a switch to the smectic A phase. The D-π-A-type π-conjugated mesogen exhibits photoluminescence, not only in solution and in the crystalline phase, but also in the mol. aggregated structure of the LC phase. In the experiment, the researchers used 4-Bromobenzonitrile(cas: 623-00-7Application of 623-00-7)
4-Bromobenzonitrile(cas: 623-00-7) is classified as organic nitriles, which are commonly use solvents and are reacted further for various applications such as manufacture of polymers and intermediates for pharmaceuticals and other organic chemicals,Application of 623-00-7 It can also be used as an aryl halide test compound in developing greener reaction conditions for Suzuki cross-coupling between aryl halides and phenyl boronic acid.
