摘要:
合成了新的pyr-苯并咪唑共轭物,其中包含不同的π-连接基,例如苯基,噻吩和三芳基胺,并通过光物理,电化学,热和电致发光研究对其进行了表征。含三芳基胺的染料由于在激发态下从三芳基胺供体到pyr受体的明显分子内电荷转移(ICT),显示出红移的吸收光谱和发射光谱中的正溶剂溶变色。所有衍生物均用作呈现深蓝色电致发光的多层有机发光二极管中的发射掺杂剂。利用1-苯基-2-(吡喃-1-基)-1 H-苯并[ d]制得的溶液加工装置作为发射体的咪唑显示出有希望的深蓝色发射特性,其最大亮度为714 cd m -2,外部量子效率为1.5%,在100 cd m -2时的CIE坐标为(0.16,0.05),色彩饱和度为100%。
