Abstract
The synthesis, optical, thermal, and photoelectrical properties of new thiophene-based hydrazones are reported. The ionization potentials of the films of thiophene-based hydrazones, measured by the electron photoemission technique, range from 4.99 to 5.58 eV. Hole-drift mobilities in the solid solutions in bisphenol-Z polycarbonate (PC-Z) of the synthesized hydrazones were studied by time of flight technique. Room temperature charge mobilities in the solid solution of 5,2″-diformyl-2,2′:5′,5″-terthiophene di(N,N-diphenylhydrazone) in PC-Z exceeded 10−5 cm2/Vs at high applied electric fields.
