表现出热激活延迟荧光（TADF）的发射体由于能够实现100%的内部量子效率，因此在有机发光二极管（OLED）的商业应用中引起了人们的兴趣。然而，除了这些材料的固有特性之外，重要的是要了解分子如何相互作用以及这些相互作用何时发生。这种相互作用导致光致发光和电致发光的显著红移，使得它们在商业用途上不太实用。通过对有机发光体中的固态溶剂化效应和聚集体效应的文献综述，为全面研究TADF发光体提供了一个框架。
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.
