Synthesis and characterization of new type photoluminescent, bulk copolymers of 2,7-(2-hydroxy-3-methacryloyloxypropoxy)naphthalene (2,7-NAF.DM) with different vinyl comonomers (methyl methacrylate, 2-hydroxyethyl methacrylate, butyl acrylate, divinylbenzene, styrene and N-vinyl-2-pyrrolidone) are presented. The chemical structure of 2,7-NAF.DM was confirmed by NMR, GC-MS and elemental analysis. The copolymers were characterized by ATR and thermal (differential scanning calorimetry) analyses. Their luminescent properties were studied in terms of quantum efficiency (Φ abs ), which was shown to change in the range of 50-90% depending on the type of comonomer. It was found that the green-emitting species in these polymers can be excited directly by low-energy (400-520 nm) photoirradiation. These materials can be applied in the liquid or solid states in the form of powders, films or monoliths.
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.
