Di(9-alkylcarbazol-3-yl)arylamines as Electroactive Amorphous Materials for Optoelectronics
摘要:
Star-shaped molecules of di(9-alkylcarbazol-3-yl)arylamines were synthesized and found to constitute new glass-forming materials with glass transition temperatures ranging from 40 to 147 degrees C. The electron photoemission spectra of the molecular glasses were recorded and ionisation potentials of 4.9-5.0 eV were established. Room temperature time of flight hole drift mobilities of the di(9-alkylcarbazol-3-yl)phenylamines molecularly dispersed in polycarbonate-Z approached 5.10(-6) cm(2)/Vs at high electric fields. Some of the compounds were converted to cross-linkable derivatives, which are potential components for insoluble charge transport layers.
