Abstract

The development of novel, efficient and cost-effective emitters for solid-state lighting devices (SSLDs) is ubiquitous to meet the increasingly demanding needs of advanced lighting technologies. In this context, the emergence of thermally activated delayed fluorescence (TADF) materials has stunned the photonics community. In particular, inorganic TADF material-based compounds can be ad hoc engineered by chemical modification of the coordinated ligands and the type of metal centre, allowing control of their ultimate photo-/electroluminescence properties, while providing a viable emitter platform for enhancing the efficiency of state-of-the-art organic light-emitting diodes (OLEDs) and light-emitting electrochemical cells (LECs). By presenting an overview of the state of the art of all metal complex-based TADF compounds, this review aims to provide a comprehensive, authoritative and critical reference for their design, characterization and device application, highlighting the advantages and drawbacks for the chemical, photonic and optoelectronic communities involved in this interdisciplinary research field.

基于金属复合物的 TADF：设计、表征和照明设备

为了满足先进照明技术日益增长的需求，为固态照明设备（SSLDs）开发新型、高效、经济的发射器已变得无处不在。在此背景下，热激活延迟荧光（TADF）材料的出现震惊了光子学界。特别是，基于 TADF 材料的无机化合物可以通过化学修饰配位体和金属中心的类型来特别设计，从而控制其最终的光/电致发光特性，同时为提高最先进的有机发光二极管（OLED）和发光电化学电池（LEC）的效率提供了一个可行的发射器平台。本综述概述了所有基于金属络合物的 TADF 化合物的最新进展，旨在为这些化合物的设计、表征和器件应用提供全面、权威和重要的参考资料，突出强调了这一跨学科研究领域的化学、光子和光电界的优势和不足。
