Abstract

New polymeric hydrazones were prepared by polycondensation of bis(4-hydrazinophenyl)sulfone with the differently substituted diformyl carbazoles. Their optical, thermal and photoelectrical properties were studied and compared with those of the new and earlier synthesized low-molar-mass glass-forming diphenylsulfone dihydrazones. The glass transition temperatures of the studied compounds range from 22 to 123˚C. The ionisation potentials of the films of diphenylsulfone hydrazone compounds measured by the electron photoemission technique range from 5.00 to 5.88 eV. Hole-drift mobilities in the amorphous films of the solid solutions of one diphenylsulfone dihydrazone in bisphenol Z polycarbaonate exceed 10-5 cm2/(Vs) at high applied electric fields as characterized by the time-of-flight method..
