A series of novel host materials based on the 10,11-dihydro-5H-dibenzo[b,f]azepine unit for highly efficient green and red organic light-emitting diodes

Three novel host materials (D-PY, S-CZ and S-TPA) based on the 10,11-dihydro-5H-dibenzo[b,f]azepine (AZ) motif were designed and synthesized. The donor groups, triphenylamine (TPA) and carbazole (CZ), were attached at different positions of the central core to study the effect of the variation of su...
