Abstract

The soluble styrene polymers, bearing dicarbazole, phenylcarbazole or phenyltriphenylamine side groups were investigated as a host material for green emitter in phosphorescent PLED devices. Those polymers were synthesized by free radical polymerization via azobisisobutyronitrile (AIBN) as initiator under 75° C. All of the host materials exhibit high thermal stability with high decomposition (Td, 5% weight loss> 398° ...
