研究领域

"" （1）基于新的发光原理的有机发光材料与器件：比如由我们首次提出并实现的双重态激子发光的有机电致发光器件（OLEDs），开发与之对应的中性共轭自由基发光材料。（2）由分子间弱相互作用诱导的有机共轭分子的自组装过程，并研究自组装的纳米结构的光电性质。（3）有机半导体材料与器件所特有的磁场效应，并利用磁场效应作为工具，研究有机光电器件内的物理过程。 """与传统闭壳荧光分子不同，中性有机共轭稳定发光自由基的最高单占分子轨道(SOMO)上只有一个电子，分子处于基态和激发态时均为双重态（doublet），故分子受激发产的激子跃迁返回基态时不会受到电子自旋禁阻的限制。我们课题组首次提出以有机发光自由基作为发光层制备有机电致发光器件（OLEDs），其内量子效率理论上可以达到100%。"
