Abstract
ABSTRACT 9-(4-methoxyphenyl)carbazolyl-containing hydrazones were prepared by multi-step synthetic route including Ullmann coupling of carbazole with 4-iodoanisole, formylation of 9-(4-methoxyphenyl)carbazole by Vilsmeier reaction and the condensation of mono- or dicarbaldehydes obtainexd with differently substituted hydrazines. All the hydrazones synthesized form glasses with the glass transition temperatures ranging from 56 to 110°C. Their ionization potentials established by electron photoemission technique are in the range 5.3–5.47 eV. Hole drift mobilities of 50% solid solutions of the hydrazones in polycarbonate established by the xerographic time-of-flight technique exceed 10−5 cm2/Vs at high electric fields.
