Description
Summary:Hole transporting glass-forming low-molar-mass hydrazones containing 9-phenylcarbazole moiety were synthesized and characterized by NMR-, infrared- and mass spectrometries. The thermal, optical and photoelectrical properties of the synthesized compounds are reported. Compounds containing 1,3-benzendithiol linking bridge were isolated as amorphous materials therefore differential scanning calorimetry experiments revealed glass transitions approximately at 60...C. The ionization potentials of the synthesized compounds were measured by electron photoemission technique in air range from 5.23 eV to 5.4 eV. Hole drift mobilities in the films of the solid solutions of some of the synthesized hydrazones in bisphenol Z polycarbonate measured by the time-of-flight technique exceed 10... cm...
