Owing to the faster response time, wider viewing angle and thinner thickness of organic light emitting diodes (OLEDs) than the conventional displays, the development of high‐efficiency light‐emitting materials has become the focus of attention. In recent years, the TADF materials have aroused widespread attention and experienced rapid development as an emitter in OLEDs, since the maximum internal quantum efficiency can reach 100% theoretically. TADF materials have exhibited the potential to be a low‐cost alternative to expensive phosphorescent luminophors. Whereas, the high resolution displays must endow the characteristics of stable and efficient panchromatic emission. The chemical structure of TADF materials are generally composed of electrical donor and acceptor, the emission colors and efficiency can be adjusted by the charge transfer between them. In this paper, TADF emitters with different emission colors are reviewed, accompanied with the investigation on their molecular design strategies and photophysical properties. In addition, the development direction and application of TADF materials are prospected.

调节施主与受主之间的强度，蓝到红热激活延迟荧光分子的结构设计

由于比传统显示器具有更快的响应时间，更宽的视角和更薄的有机发光二极管（OLED）厚度，因此高效发光材料的开发已成为关注的焦点。近年来，由于最大内部量子效率理论上可以达到100％，因此TADF材料作为OLED的发射器引起了广泛的关注并经历了快速发展。TADF材料已显示出可作为昂贵磷光发光体的低成本替代品的潜力。高分辨率显示器必须具有稳定和有效的全色发射特性。TADF材料的化学结构通常由电子供体和受体组成，可以通过它们之间的电荷转移来调节发光颜色和效率。本文综述了具有不同发射颜色的TADF发射体，并对其分子设计策略和光物理性质进行了研究。另外，展望了TADF材料的发展方向和应用前景。
