Abstract:The spiro-type bulky architecture in the polymer is intriguing since it can suppress the interchain interactions and enhance the photoluminescence efficiency. A new triphenylamine-substituted PFO/PPV alternating copolymer was synthesized by using a typical Heck-coupling reaction. This highly soluble polymer exhibits strong photoluminescence with maximum emission peaks centered at 417 and 441 nm in THF; 425 and 460 nm in benzonitrile. In deoxygenated dry benzonitrile, the fluorescence time profile of copolymer … 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.
