合成了一系列具有给体-受体-给体结构的近红外有机发色团。该材料具有良好的热稳定性和较强的固态光致发光性能，适合应用于发光二极管。在1080 nm处获得了唯一的近红外发射，外量子效率为0.28%。电致发光波长最长为1220nm。
A series of NIR organic chromophores with donor-pi-acceptor-pi-donor structure are synthesized. Good thermal stability and strong photoluminescence in solid state render them suitable for application in light-emitting diodes. Exclusive near-infrared emission at 1080 nm with external quantum efficiency of 0.28% is obtained from the nondoped OLEDs. The longest electroluminescence wave-length is 1220 nm.
