(Bi)phenyl-substituted carbazoles containing reactive functional groups were synthesized by the multi-step synthetic rout. The monomers were examined by various techniques including thermogravimetry, differential scanning calorimetry, UV and fluorescence spectrometry as well as electron photoemission technique. These derivatives were also tested as hole transporting materials in bilayer OLEDs with Alq(3) as the emitter. The devices exhibited promising overall performance with a turn-on voltage of similar to 3 V. a maximal photometric efficiency of 5.1 cd/A and maximum brightness of 12,200-15,600 cd/m(2).
