A novel class of hydrogen bonding liquid crystalline benzoic acids with alkylthio groups was established and their phase transition behavior was investigated in detail.
A homologous series of alkylthio- and alkoxy-based asymmetric calamitic liquid crystal (LC) molecules was developed. The effects of alkylthio groups on the phase transition properties and unexpected intercalated LC phase structures were studied.
We offer novel hydrogen-bonded liquid crystalline complexes between 4-alkylthiobenzoic acids and 4-phenylpyridine. Although similar molecular systems connected with ester linkages or covalent bonds do not show any mesophases, the present complexes show nematic phase, indicating that hydrogen bonding has a significant role in mesogenic incidence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
