Compounds , , , , and were conveniently synthesized, and they were found to exhibit TADF properties with lifetimes of 857, 575, 561, 768, and 600 ns, respectively. These short lifetimes of the compounds might be due to the combination of small singlet-triplet splitting energy (Δ) and benzoate group, which could be an efficient strategy for the further design of short-lifetime TADF materials.
化合物、、、和的合成简便，且发现它们具有热活化延迟荧光（TADF）特性，其寿命分别为857、575、561、768和600纳秒。这些化合物的短寿命可能归因于单重态-三重态分裂能（Δ）小和苯甲酸酯基团的组合，这可能是进一步设计短寿命TADF材料的有效策略。
