Luminescent sensitization and blue shift emission of Ir(ppy)2(VPHD) by copolymerization with MMA

► PMMA-Ir(ppy)2(VPHD) as luminescent material with high yield of 53%.► The blue color emission at 489 nm from 1MLCT in conformity with Lorenz function.► The quantum yield for the copolymer increases 45% than that of the iridium monomer.► The 3MLCT Ex. intensity versus the monomer concentration is in conformity with Boltzmann function.
