Abstract

Alcohol-soluble 2, 7-carbazole-1, 4-phenylene copolymers PCP-NOH and PCP-EP, comprising surfactant-like diethanolamino and phosphonate end groups on the side chains, respectively, were synthesized and utilized as electron injection layer (EIL) in combination with high work function Al electrode in polymer light-emitting diodes (PLEDs). The UV–vis absorption and photoluminescence properties of the PCP-NOH and PCP-EP are mainly ...
