Monomers and polymers of indole-based enamines as amorphous electro-active materials

摘要

Indole-based enamines containing reactive functional groups were synthesized by the multi-step synthetic route. Full characterization of their structure is presented. The monomers were subjected to cat-ionic ring opening polymerization using BF_3 • O(C_2H_5)_2 as an initiator. The synthesized monomers and polymers were examined by various techniques including differential scanning calorimetry, UV spec-trometry, electron photoemission and time of flight techniques. The electron photoemission spectra of the layers of the synthesized materials showed the ionization potentials of 5.55-5.7 eV. Hole drift mobilities in the 50% molecular dispersions of the synthesized epoxy monomers in bisphenol Z polycarbonate range from 4.2 × 10~(-6) to 1.2 × 10~(-5) cm~2/Vs at high electric fields as it was established by xerographic time of flight technique.
