Triazine-based aromatic amines as new glass-forming charge transport materials
Various diarylamino-substituted 1,3,5-triazine deriuatives have been. synthesized by Cu catalyzed Ullmann-type arylamino-aryl coupling reaction. Full characterization of the compounds structures by mass spectrometry, IR and electronic absorption, as well as (1)H NMR spectroscopy is presented. Some of the compounds represent amorphous materials with glass transition temperatures exceeding 84 degrees C and with thermal decomposition starting at temperatures > 330 degrees C. The electron photoemission spectra of the materials were recorded and the ionisation potentials of ca. 5.3-5.8eV were established. Tune-of-flight hole drift mobility of some diarylamino-substituted triazines molecularly dispersed in bisphenol Z polycarbonate approached 10(-5) cm(2)/Vs at high electric field.
