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

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 cationic ring opening polymerization using BF3 center dot O(C2H5)(2) as an initiator. The synthesized monomers and polymers were examined by various techniques including differential scanning calorimetry, UV spectrometry, electron photoemission and time of flight techniques. The electron photoemission spectra or the layers of the synthesized materials showed the ionization potentials of 5.55-5.7 eV, Hole drift mobilities in the 50% molecular dispersions or the synthesized epoxy monomers in bisphenol Z polycarbonate range from 4.2 x 10(6) to 1.2 x 10(5) cm(2)/Vs at high electric fields as it was established by xerographic time of flight technique.
