我们合成了一种红荧烯的衍生物,2-甲酰基红荧烯,作为一种红光掺杂剂,掺杂在N,N-diphenyl-N,N-bis1-naphthyl–1,1-biphenyl-4,4-diamine(NPB)中制备的电致发光器件,发射峰位于598nm,电流效率为2.1cd/A。用这个红光掺杂系统制备了一个白光电致发光器件,在白光器件中,2-甲酰基红荧烯,八-羟基喹啉铝(Alq3),以及NPB分别组成了白光中的红、绿以及蓝的发光成分,获得了一个白光器件,该器件显色指数高达89.8,在11V的时候,色坐标达(0.33,0.33)、最大亮度为5000cd/m2以及最大发光效率为4.7cd/A。这些性能参数表明这个白光器件具有潜在的照明应用。另外,还讨论了器件的结构设计以及电致发光过程及机理。

A rubrene (Ru) derivative, 2-formyl-rubrene was synthesized and was used as reddopant in N,N'-bis- (1-naphthyl)-N, N '-diphenyl-1, 1'-biphenyl- 4, 4 '-diamine (NPB) host in organic light-emitting devices (OLEDs) that offers an emission peak at about 598nm and a current efficiency of 2. lcd/A. The red emitter was also used to fabricate a white OLED (WOLED), in which 2-formyl-rubrene, tris (8-hydroxyquinoline) alumi- num (Alq3) and NPB contribute to the red, green and blue emissive components respectively. As a result, a high color rendering index of 89.8, CIE coordinates of (0.33, 0.33) at llV as well as a maximum luminance of 5000cd/m2 and a luminance efficiency of 4.7cd/A were obtained. The performances suggest its potential appli- cations for solid-state lighting. Also, the design and electroluminescent processes of the WOLED based on 2- formyl-rubrene were also discussed.
