Abstract
Reaction of N-phenyl methacrylamide ( N-phMA) with (ppy) 2Ir(μ-Cl) 2Ir(ppy) 2 (ppy = 2-phenylpyridine) in dichloromethane at the present of sodium methoxide at room temperature yields Iridium(III)-containing complex (ppy) 2Ir( N-phMA) in which a N-substitued acrylamide was firstly applied as ancillary ligand. Complex (ppy) 2Ir( N-phMA) can readily copolymerized with the commonly used N-vinyl carbazole (VK) for PLED materials in different feed ratios to generate a series of metal-containing polymers poly(VK-(ppy) 2Ir( N-phMA))s whose chemical structures are well-defined. Investigations of thermal and photophysical properties indicate that these polymers are of interest materials for PLED.
