摘要

在这项研究中，我们研究了三种发光原- TN， TA和TP的聚集诱导延迟荧光（AIDF）性质。我们的综合理论分析显示，在~µs的时间尺度上，聚合态或固态态的∆EST显著降低，激活TADF。此外，由于其强电荷转移特性和较长的单重态激子寿命，这些发光源表现出双光子激发的反斯托克斯光致发光发射和改进的光电流产生。

Multifunctional luminogens with synergy of aggregation-induced delayed fluorescence, two-photon absorption and photocurrent generation†

In this study, we investigated the aggregation-induced delayed fluorescence (AIDF) properties of three luminogens – , , and . Our comprehensive theoretical analysis reveals a significant reduction in the ΔE_ST in their aggregated or solid-state, activating TADF, on a ∼μs time-scale. Additionally, these luminogens demonstrate two-photon excited anti-Stokes photoluminescence emission and improved photocurrent generation, attributed to their strong charge transfer characteristics and longer singlet exciton lifetimes.
