✦ Synopsis

Abstract

Three polytriphenylene derivatives with phenyl and alkyl groups as side chains have been tested as blue light emitters. The best performance in terms of turn‐on voltage and luminance efficiencies was obtained for poly(2‐heptyl‐3‐(4‐octylphenyl)‐1,4‐diphenyl‐6,11‐triphenylenyl‐1,4‐benzene) (1), which was additionally blended with an electron‐transporting and a hole‐injection material in the device, and had an onset of 4.6 V and reached 0.73 cd · A^−1^.

A novel class of hosts suitable for solution processing has been developed based on a conjugated dendritic scaffold. By increasing the dendron generation, the highest occupied molecular orbital (HOMO) energy level can be tuned to facilitate hole injection, while the triplet energy remains at a high
