摘要：

The synthesis of a series of new glass-forming hydrazones containing carbazole and diphenylamine moieties is reported. The thermal, optical and photoelectrical properties of mono-, di- and tetra-substituted compounds are compared. The glass transition temperatures of the newly synthesized hydrazones range from 75 to 145 degrees C. The ionization potentials of the films of hydrazones, measured by the electron photoemission technique, range from 4.74 to 5.15 eV. Hole-drift mobilities of the solid solutions of hydrazones in bisphenol Z polycarbonate (50 wt.%) are in the range of 6.3 x 10(-6) to 1.1 X 10(-5) cm(2)/Vs at electric field of 6.4 x 10(5) V/cm as characterized by the time-of-flight method.
