We report the charge transport characteristics of dibenzothiophene phenylenediamine copolymer (DBT-PD). Fig. 1 shows DBT-PD (Mw = 77,000) which is a 50:50 molar ratio random copolymer consisting of DBT and a hole-transporting phenylenediamine group with tertiarybutyl substituents. The quoted ratio i...
