[3,3 ']Bicarbazolyl-based enamines as hole-transporting materials

[3,3']Bicarbazolyl - based enamines have been synthesized by the multi-step synthetic rout. Full characterization of their structure by nuclear magnetic resonance and mass spectrometry as well as by infrared spectroscopy is presented. The synthesized materials were examined by various techniques including differential scanning calorimetry, ultraviolet and photoluminescent spectrometry, electron photoemission spectrometry and time of flight techniques. Electron photoemission spectra of the amorphous layers of the synthesized enamines revealed the ionization potentials of ca. 5.5 eV. Time-of-flight hole drift mobilities in the layers of bisphenol Z polycarbonate molecularly doped with 33 - 50 wt. % of [3,3']-bicarbazolyl - based enamines ranged from 10(-5) to 10(-4) cm(2)/Vs at high electric fields.
