phosphorescence centered at 530∼555 nm, yet red‐shifted to ∼660 nm in a concentrated solution or in the solid state. This series of compounds can be used as emitting dyes in light‐emitting diodes (LED). The LED devices with a configuration ITO/NPB/dye (6%) in CBP/BCP/AlQ3 or TPBI/LiF/Al displayed a yellow to red color, where NPB, CBP, BCP, AlQ3 and TPBI denote 4,4′‐bis[N‐(1‐naphthyl),N‐phenylamino]biphenyl
4-羟基-1,5-萘啶(HNt)是8-羟基喹啉的衍生物,但HOMO和LUMO的带隙比后者宽。铂(II)与Nt的环金属配合物呈正方形规划几何形状,并且在冷凝介质中极有聚集的趋势。通过检查其在不同浓度下的光致发光光谱可以验证这种现象。在稀溶液中,它呈现黄色荧光,中心在530-555 nm之间,但在浓溶液或固态下红移至660 nm。该系列化合物可用作发光二极管(LED)中的发光染料。在CBP / BCP / AlQ 3或TPBI / LiF / Al中配置ITO / NPB /染料(6%)的LED器件显示黄色到红色,其中NPB,CBP,BCP,AlQ 3和TPBI分别代表4,4'-双[ N-(1-萘基),N-苯基氨基]联苯,4,4'-双(咔唑-9-基)联苯,2,9-二甲基-4,7-二苯基-1,10-菲咯啉,三(8-羟基喹啉基)铝和2,2',2''-(1,3,5-苯三基)三(1-苯基-1 H-苯并咪唑)。最大光强度超过2
