In this research, pyreno[4,5‐c:9,10‐c′]difuran and its analogues have been successfully synthesized through a one‐step reaction using the same precursor and their physicochemical properties were studied. UV/Vis, fluorescence and CV measurements illustrated that the inserted chalcogen atoms (O, S and Se) brought almost no change on the photochemical and electrochemical properties whereas TM‐2N‐CH3 exhibited more blue‐shifted fluorescence emission and simultaneously elevated HOMO energy level.
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.
