| 英文摘要 | Twin compounds containing two phenylethenyl substituted indole rings were synthesized by a short multi-step synthetic route. The derivatives were characterized by thermo-gravimetric analysis, differential scanning calorimetry and electron photoemission technique. The materials were found to show very high thermal stability having initial thermal degradation temperatures in the range of 385-390 degrees C. Glass transition temperatures of the amorphous molecular materials were in the rage of 62-95 degrees C. The electron photoemission spectra of thin layers of the derivatives showed ionization potentials in the range of 5.4-5.5 eV. Hole drift mobilities in thin layers of these derivatives exceed 6.4 x 10(-5) cm(2)V(-1)s(-1) at high electric fields at room temperature. These materials have been tested as hole transporting layers in electroluminescent bilayer OLEDs with Alga as the emitter. The device with hole transporting layer comprised of 1,4-di[3-(2-phenylethenypindo1-1-yl]butane exhibited the best overall performance with low turn-on voltage of 3.4 V, a maximum luminance efficiency of 3 cd/A and maximum brightness of about 1400 cd/m(2).
