手性热激活延迟荧光（TADF）材料作为一类兼具手性和TADF性质的新型手性发光材料，在电致圆偏振发光器件（CP-OLED）、3D显示等领域有重要的应用前景，有望成为新一代显示材料。本项目通过在各种类型的手性骨架上引入高效TADF片段，并利用一系列官能团化反应，设计合成几类具有不同结构类型、不同发光颜色的手性小分子和聚合物等新型高效手性TADF材料。通过深入研究手性TADF材料的手性、光电性能等性质以及分子构效关系，并结合相关的理论计算模拟，为进一步设计性能更优异的手性TADF材料提供依据和指导策略。同时，基于本项目设计合成的手性TADF材料，并结合高效OLED器件的制备，创新性地开展兼具高器件效率和强电致CPL性质的高效CP-OLED研究。通过本项目的研究，不仅有助于开发新型手性发光材料和高效CP-OLED，还对手性发光分子在新一代显示材料等功能化应用领域的研究具有重要的创新推动作用。

Chiral thermally activated delayed fluorescence (TADF) materials, as a new kind of highly efficient chiral luminescent materials with both chiral and TADF properties, have extensive potential applications in CP-OLED and 3D display, which is expected to be a new generation of display materials. In this project, combining with a series of derivatization, we will ingeniously introduce the TADF unit into various types of chiral skeletons for creation of innovative chiral TADF materials with various structures and luminescent colors. By in-depth study of chirality, optoelectronic properties, and structure-activity relationships of obtained chiral TADF materials, combining with theoretical simulations, we will provide a general strategy for designing new chiral TADF materials with superior performance. Subsequently, based on our previous research on high-efficiency OLED, we will use the chiral TADF material developed in this project to conduct innovative research on high-efficiency CP-OLED with both high device efficiencies and strong circularly polarized electroluminescence. Based on the above, the outcomes of this program will not only be benefit for developing new luminescent materials and high-efficiency CP-OLED, but also play an important role in the functional application of chiral molecule as well as the development of new generation of display materials.
