以吡喃腈作为电子受体、吲哚啉作为电子给体单元, 合成了一种吲哚啉衍生物DADIN作为高色纯度的红色掺杂型电致发光材料, 并对其溶液特性和有机电致发光器件性能进行了研究. 相对于柯达公司经典掺杂型红色发光材料DCJTB, 该发光材料的合成简单、提纯工艺易行、产率高, 并具有更纯正的红色发光. 研究表明, 以DADIN作为掺杂型电致发光材料的有机电致发光器件的电流效率是DCJTB的1.5倍, 实为DCJTB理想的替代品.

A red electroluminescent material DADIN with a high color purity was prepared from 4-(dicyanomethylene)-2,6-dimethyl-4H-pyran as its electron-acceptor and indoline unit as its electron-donor. With respect to the Kodak’s traditional red dopant of DCJTB, it was proved that the synthesis and purification procedures of DADIN were simple, and the yield was high. In addition, the electroluminescent device based on DADIN as doping emitter has 1.5 times of current efficiency as DCJTB with high color saturation, indicative of a promising red emitting alternate to DCJTB.
