New reactive hole-transporting hydrazone and its adducts with diol and dithiol

Abstract

New hole-transporting hydrazone with reactive vinyloxyethyl group and its glass forming adducts with 9-ethyl-3,6dihydroxymethylcarbazole 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,Ndipheny1hydrazone 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.
