Synthesis and the properties of a series of triphenylamine- based hydrazones are reported. The dependence of their thermal and glass- forming properties on their chemical structure is discussed. The ionization potentials of the synthesized hydrazones measured by the electron photoemission technique range from 5.16 to 5.32 eV. Hole- drift mobilities of some derivatives molecularly dispersed in bisphenol Z polycarbonate exceed 10(-4) cm(2)V(-1) s(-1) at high electric fields (10(6)V/cm), at room temperature.
