Abstract:

Under ultraviolet(UV) light, the persulfurated arenes derivative 6SPh-IM exhibits 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.
