Abstract

New hole-transporting hydrazone with reactive vinyloxyethyl group and its glass forming adducts with 9-ethyl-3,6 dihydroxymethylcarbazole and 4,4’-thiobisbenzenethiol have been synthesized. The thermal stability of the synthesized compounds has been estimated and their optical, photophysical and photoelectrical properties have been studied. The ionisation potential of 5.14 eV has been established for 2-vinyloxyethyloxy-4-diethylaminophenyl-1-carbaldehyde N,N diphenylhydrazone by electron photoemission technique. Hole mobilities exceeding 10-5 cm/(V·s) at high electric fields have been observed by the time of flight technique in the 50 % solid solution of the hydrazone in bisphenol Z polycarbonate..
