Design, synthesis and properties of triple-color hyperbranched polymers derived from poly(9,9-dioctylfluorene) with phosphorescent core tris(1-phenylisoquinoline)iridium(â ¢)

Triple-color hyperbranched polymers based on poly(9,9-dioctylfluorene) (PF) with phosphorescent tris(1-phenylisoquinoline)iridium(Ш) (Ir(piq)3) as red core and poly[(9,9-dioctylfluorene-2,7-diyl)-alt-(benzo [2,1,3]thiadiazol-4,7-diyl)] (PFBT) as green segments were designed and synthesized.162
