Abstract
The present new semiconducting compds. with ≥1 optionally substituted phenazine moiety are phenazine derivs. I [R1 =halo, CN, NO2, R2, -L-R3, OH, OR2, OR3, NH2, NHR2, N(R2)2, NR2R3, etc.; L =divalent C1-40 alkyl, divalent C2-40 alkenyl, etc.; R2 =C1-40 alkyl, C2-40 alkenyl, etc.; R3 =C3-10 cycloalkylene, etc.; q =0-6 int.]. The compds. disclosed herein can exhibit high carrier mobility and/or efficient light absorption/emission characteristics, and can possess certain processing advantages such as soln.-processability and/or good stability at ambient conditions.
