Vinyloxyethyl-substituted triphenylamine-based hydrazone and its adducts with diol and dithiol as glass-forming hole transport materials

Vinyloxyethyl-substituted triphenylamine-based hydrazone and its adducts with 9-ethyl-3,6-dihydroxymethylcarbazole and 4,4′-thiobisbenzenethiol were synthesized and studied as glass-forming hole transport materials. The thermal, optical and photoelectrical properties of the synthesized materials were studied. All the synthesized compounds form glasses with the glass transition temperatures ranging from 21 to 114 °C. Their ionisation potentials established by electron photoemission technique range from 5.34 to 5.49 eV. The time of flight hole mobilities in the layers of the solid solutions of one synthesized hydrazone in bisphenol Z polycarbonate reach 10−4 cm2/V s at high electric fields.
