SummaryThe palladium-catalyzed three-component coupling polymerization of pbromophenylallene and a nucleophile possessing oligo-oxyethylene units was performed to give a poly(p-phenylene-vinylene) derivative having amphiphilic substituents on each vinylene unit in a high yield. The polymer was found to be soluble in organic solvents such as benzene, chloroform, N,N-dimethylformamide, and methanol, whose number-average molecular weight (M n ) and the molecular weight distribution (M w /M n ) were estimated as 8,600 and 1.76, respectively.
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.
