Macrocyclic Engineering of Thermally Activated Delayed Fluorescent Emitters for High‐Efficiency Organic Light‐Emitting Diodes (Adv. Mater. 39/2023)

Thermally Activated Delayed Fluorescence In article number 2301929, Yingxiao Mu, Yanping Huo, Shi-Jian Su, and co-workers report a series of π-conjugated macrocyclic luminescent materials with thermally activated delayed fluorescence properties by a modular substitution strategy. They further reveal the characteristics of the highly luminescent π-conjugated compounds by detailed analysis of their photophysical properties, such as excited state modulation through substitution positions or substitution of the donor and acceptor modules.
