摘要： 在紫外光照下，多硫芳烃衍生物6SPh-IM具有光激发诱导分子聚集的效果。同时，研究发现其能够带动生物大分子实现组装体的聚集状态的变化。在光照下组装体的发射光谱、粒径和圆二色信号表现出差异，并在透射电镜下呈现出自组装形貌的调控。这种通过光诱导分子运动带动系统形貌变化的策略将为自组装调控提供新思路。

Abstract: Under ultraviolet (UV) light, the persulfurated arenes derivative 6SPh-IM exhibi photoexcitation-induced assembly (PEIA) effect. The study further reveals its ability to drive the change of the aggregation state of the biomacromolecule assembly. Under UV irradiation, the aggregated system demonstrates distinct emission spectra, particle size distributions, and circular dichroism (CD) signals, with transmission electron microscopy (TEM) revealing controllable self-assembly morphologies. This strategy of inducing molecular motion upon UV irradiation to modulate system morphology provides novel insights for self-assembly regulation.

Key words: Light modulation, Self-assembly, Aggregation-induced emission, Persulfurated arenes
