High-performance organic electroluminescent devices based on two new siloles, 1,1-dimethyl-2,5-bis(p-2,2′-dipyridylaminophenyl)silole (5) and 1,1-dimethyl-2,5-bis(p-2,2′-dipyridylaminophenyl)-3,4-diphenylsilole (8), acting as both electron- and hole-transporting material, are described. The best performance is attained with silole 8, which displays a luminescence of 104 Cd m−2 at 10 V for a current density of less than 0.2 A cm−2, which is as efficient as tris(8-hydroxyquinoline)aluminium (Alq3), one of the best candidates for electroluminescent materials under the same conditions.
本文介绍了基于 1,1-二甲基-2,5-双(p-2,2′-二吡啶基氨基苯基)硅烯 (5) 和 1,1-二甲基-2,5-双(p-2,2′-二吡啶基氨基苯基)-3,4-二苯基硅烯 (8) 这两种新型硅烯的高性能有机电致发光器件,它们既是电子传输材料,也是空穴传输材料。硅ole 8 的性能最佳,在电流密度小于 0.2 A cm-2 的情况下,10 V 电压下的发光强度为 104 Cd m-2,与三(8-羟基喹啉)铝 (Alq3)不相上下,而 Alq3 是相同条件下电致发光材料的最佳候选材料之一。
