Synthesis and properties of novel triphenylamine polymers containing ethynyl and aromatic moieties

Abstract

Novel polymers composed of TPA (triphenylamine), ethynyl and aromatic units in the main chain were synthesized. These polymers are structurally rigid due to aromatic and acetylene moieties and show high T-g and thermal stability. The polymers 3a and 4 are cross-linked on annealing at similar to 220 degreesC and they can be potentially used as a hole-transporting material for multi-layer devices with spin-coating.
