摘要:
Hydrazones containing electron-accepting 1,8-naphthalimide species and electron-donating triphenylamino moieties were synthesized and characterized by nuclear magnetic resonance, infrared spectroscopy, and mass spectrometry. Thermal, optical, electrochemical and photophysical properties of the synthesized derivatives were investigated, their, optical and electrochemical band-gap energies and ionization potentials were established. The hydrazones exhibit initial mass loss temperatures in the range of 268-348 degrees C and can form glasses with glass transition temperatures in the range of 46-142 degrees C as established by differential scanning calorimetry. Room temperature time-of-flight hole mobilities in the solid solutions of the derivatives in the polymeric host bisphenol-Z polycarbonate (50%) exceeded 10(-5) cm(2)/V s at high applied electric Fields.
