摘要：

Ter- and quaterthiophenes bearing pyrenes at the terminal alpha or beta positions have been synthesized as novel emitting materials in organic electroluminescence devices. The efficient sin gle-layer EL devices of these compounds are fabricated by use of an A1/ultrathin LiF bilayer cathode. One of them exhibits a maximum luminance of 1860 cd/m(2) and a luminous efficiency of 0.15 1m/W, which are of the highest performance class among single-organic-layer EL devices.
