Oxetanyl-functionalized 9-aryl[3,3′]bicarbazolyl derivatives as building blocks for electro-active polymers

摘要

9-Aryl[3,3′]bicarbazolyl derivatives 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 and time of flight techniques. The electron photoemission spectra of the layers showed the ionisation potentials of 5.2-5.5 eV. Time-of-flight hole drift mobilities in amorphous layers of bisphenol Z polycarbonate containing 50 wt. % of the electroactive materials exceed 10~(-5) cm~2/Vs at high electric fields.
