Abstract:Hyperbranched conjugated polymers (P1, P2 and P3) containing different aryl groups appended with carboxylic ester groups were synthesized by metal‐free catalyzed polymerization via A2 + B3 type monomers. These as‐prepared polymers can be dissolved well in common organic solvents and have good thermal stability. These polymers were investigated as fluorescence chemosensor for the detection of biologically important metal ion Fe3+. The corresponding Stern‐Volmer constants (Ksv) of P1, P2 and P3 were 3.99 × 104 M… 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.
