Abstract
Vinyloxyethyl-substituted carbazole-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 20 to 109 °C. Their ionisation potentials established by electron photoemission technique range from 5.29 to 5.46 eV. Time-of-flight hole mobilities in the layers of the solid solutions of one synthesized hydrazone in bisphenol Z polycarbonate exceeds 10−5 cm2/(V s) at high electric fields.
