Compared to the universal photochemical mechanism in photoactivation, the photophysical-dominant behavior is rarely reported. In this study, a luminogen with aggregation-induced emission characteristic named TIOdB with a double-ionized framework was prepared, and it exhibited an obvious photoactivation phenomenon with continuous light irradiation. Employing a series of spectral and electro experiments, the morphology and crystal analyses, and theoretical simulation, the potential mechanism of photo-induced crystallization with emission enhancement (PICEE) is presented to illuminate this photoactivation process, which offered a novel strategy for the IN SITU formation of nanocrystals. Particularly, the linear relationship between the illumination intensity and fluorescence enhancement of TIOdB was revealed, which has the potential to optimize plant growth conditions. Besides, TIOdB could be used as a high-quality mitochondrion imaging probe with the light-activated property and cancer cell killing performance.

具有发射增强作用的光致结晶（PICEE）

与光活化中的普遍光化学机理相比，很少有光物理行为的报道。在这项研究中，制备了具有聚集诱导发射特性的具有双电离骨架的TIOdB发光剂，并在连续光照射下表现出明显的光活化现象。通过一系列的光谱和电学实验，形态学和晶体分析以及理论模拟，提出了具有发射增强作用的光致结晶（PICEE）的潜在机理，以阐明这种光活化过程，这为IN SITU提供了新的策略纳米晶体的形成。特别是，揭示了光照强度与TIOdB的荧光增强之间的线性关系，这具有优化植物生长条件的潜力。此外，TIOdB可以用作具有光激活特性和癌细胞杀伤性能的高质量线粒体成像探针。
