Emitters that exhibit thermally activated delayed fluorescence (TADF) are of interest for commercial applications in organic light-emitting diodes (OLEDs) due to their ability to achieve internal quantum efficiency of 100%. However, beyond the intrinsic properties of these materials it is important to understand how the molecules interact with each other and when these interactions may occur. Such interactions lead to a significant red shift in the photoluminescence and electroluminescence, making them less practicable for commercial use. Through summarizing the literature, covering solid-state solvation effects and aggregate effects in organic emitters, this mini review outlines a framework for the complete study of TADF emitters formed from the current-state-of-the-art techniques.
由于能够实现100%的内量子效率，具有热激活延迟荧光（TADF）的发光体在有机发光二极管（OLED）的商业应用中备受关注。然而，除了这些材料的固有特性外，了解分子如何相互作用以及这些相互作用何时可能发生也很重要。这种相互作用会导致光致发光和电致发光出现显著的红移，使其在商业应用中不太可行。通过总结涵盖有机发光体中固态溶剂化效应和聚集效应的文献，本综述概述了一个利用当前最先进技术对TADF发光体进行全面研究的框架。
