Glass-forming hole-transporting carbazole-based hydrazone monomers, polymers, and twin compounds
摘要:
The synthesis, optical. thermal, and photoelectrical properties of new carbazole-based hydrazone monomers, polymers, and twin compounds are reported. All the synthesized materials are capable of glass formation. Their glass transition temperatures range from 27 to 90 degrees C. The ionization potentials of the films of carbazole-based hydrazones measured by the electron photoemission technique range from 5.18 to 5.48 eV. Hole-drift mobilities in the amorphous films of the synthesized hydrazone monomers measured by the time-of-flight technique at room temperature reach 10(-4) cm(2)/(V s) at high applied electric fields.
