Abstract:Four D-π-A push-pull derivatives either based on a diphenylmethylamine or a 9-methylcarbazole electron-rich block (D), connected to a dicyanovinyl accepting moiety (A) through two different spacers (π), namely a thiophene or selenophene, were synthesized and characterized. These small and synthetically accessible molecules were indeed selected to rationalize the impact of both i) the rigidification of the arylamine part and ii) the nature of the π-spacer constituting heteroatom on the optical, electrochemical,… Show more
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.
