摘要
A new silole derivative, 1,2,3,4,5-pentaphenyl-1-(8-phenyl-1,7-octadiynyl)silole, is synthesized, characterized, and used as the electron-transport/emission layers in organic light-emitting diodes. Blue emission at 492 nm is observed, with a maximum luminance of 10460 cd/m(2) at 18 V. The respective maximum current and power efficiencies are 8.47 cd/A and 3.8 lm/W. A triple-layer composite cathode was used, consisting of tris(8-hydroxy-quinolne)aluminum (Alq(3)) lithium fluoride and aluminum. The dependence of emission efficiency on the thickness of TPD and Alq(3) is investigated and explained.
