摘要 荧光OLED材料由于受到激子统计规律的限制,其能量利用效率小于25%.为了开发高效而价廉的OLED材料,突破激子统计规律的研究受到了广泛关注,目前的研究主要集中在三个方向:突破激子统计限制的共轭聚合物材料、三线态反系间窜越(RISC)的延迟荧光材料以及"热激子"(hot exciton)与杂化局域-电荷转移(HLCT)激发态材料.对近年来在基于高激子利用率的第三代有机电致发光材料的研究方面的进展情况进行综述,同时对其未来的研究前景进行了展望. Due to the limitation of exciton statistical regularity, the energy efficiency of fluorescent OLED materials is less than 25%. In order to obtain efficient and cheap OLED materials, the research breakthrough on the laws of the exciton statistics received widespread attention, and the present study mainly can be classified in three directions: the conjugated polymer materials that breakthrough the ex- citon statistical limits, the delayed fluorescence materials based on reverse intersystem crossing (RISC) and the materials based on "hot exciton" theory and hybrid-local charge transfer (HLCT) states. In this paper, the third generation organic electroluminescent materials based on high excitonutilization ratio are reviewed,
