ABSTRACT:A Novel monomer 9,I0-bis(4-hydroxy-1-butynyl)anthracene (Ml) was synthesized and some polyesters and polyurethanes containing a donor 9, 10-diethynylanthracene and acceptor pyromellitic diimide groups were prepared. The polymers were soluble in common organic solvents and gave transparent films by casting. They showed 5% weight loss at the temperature 250-300°C. All polymers showed luminescence and maximum depended on polymer composition. Polymers containing the 9,10-diethynylanthracene moiety alone showed luminescence with maximum at 470-480nm while those containing 9,10-diethynylanthracene and pyromellitic diimide groups showed luminescence with maximum around 600nm due to the charge transfer complex (CTC) formation between them. Some polymers showed electroluminescence with turn-on voltage of 10.5 V.
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.
