Abstract
The synthesis of a series of 2-(10,11-dihydrodibenz(b,f)azepinyl)carbazole-based monomers 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 monomers and polymers were examined by differential scanning calorimetry, UV spectrometry, cyclic voltammetry and electron photoemission spectrometry. The electrochemical investigation of the solutions of the synthesized compounds revealed HOMO values ranging from −5.12 to −5.06 eV. Electron photoemission spectrometry of the solid samples gave ionization potentials of 5.40–5.50 eV.
