Synthesis of a novel cationic water-soluble efficient blue photoluminescent conjugated polymer
Abstract
A novel cationic conjugated polymer, poly[(9,9-dihexyl-2,7-fluorene)-alt-co-(2,5-bis{3-[ (N,N-dimethyl)-N-ethylammonium]-1-oxapropyl }-1,4-phenylene)] dibromide, which is water-soluble and emits bright blue fluorescence both in solutions and as films, is synthesized through Suzuki coupling reaction and a post-polymerization treatment.
