Monomers and oligomers with the pendent adducts of carbazole with 5H-dibenz(b,f)azepine and its 10,11-dihydro derivative

The synthesis of a series of carbazole-based monomers incorporating dibenzazepines at the 3 position is reported. Full characterization of their structures is presented. The monomers were subjected to cationic polymerization using BF3·O(C2H5)2 as an initiator. The synthesized low-molar-mass compounds and oligomers were examined by differential scanning calorimetry, UV spectrometry, electron photoemission and time of flight techniques. The electron photoemission spectra of the films of synthesized materials revealed the ionization potentials of 5.12-5.34 eV. Hole drift mobilities of low-molar-mass compounds molecularly dispersed in bisphenol Z polycarbonate range from 2.6 × 10−8 to 1.7 × 10−6 cm2/V s at high electric fields as it was established by xerographic time of flight technique.
