Stimuli-responsive aggregation-induced emission (AIE) materials are highly sensitive and rapidly responsive to external signals, making them ideal solid for anti-counterfeiting encryption. However, the limited conformational packing variations resulting from regio-isomerization with a single substituent restricts stimuli-responsive behavior of these materials. In this work, several AIE-active regio-structural isomers based on salicylaldehyde Schiff base scaffold have been straightforwardly obtained through multiple substitutions bromide triphenylamine moieties. Solvent-effect experiments demonstrate their different orders charge-transfer excited-state intramolecular proton transfer upon photoexcitation, indicating regulation processes via multi-site isomerization. These also mechanochromism acidichromism, allowing adjustable effects. As demonstration, p-Br-TPA both acidichromism can be synergistically utilized multi-level decryption. This study successfully regulates evolution excited states isomerization, offering general approach achieving tunable properties in bases toward

Abstract Artificial aggregation‐induced emission luminogens (AIEgens) have flourished in bio‐applications with the development of synthetic chemistry, which however are plagued by issues like singularity structures and non‐renewability. The unique renewability biomass moieties can compensate for these drawbacks, but their properties hard to design regulate due confined structures. Therefore, it appears be a reasonable approach derive AIEgens from abundant (BioAIEgens), integrating bilateral advantages both natural AIEgens. In this work, blue‐violet emissive coumarin its lactone structure serving as rare acceptor, is utilized construct donor‐π‐acceptor typed BioAIE isomers incorporating propeller‐like electron‐donating triphenylamine (TPA) unit. results show that Cm‐ p ‐TPA undergoes charge transfer keto form, emitting red light at 600 nm, applied monitor Cu 2+ concentration during mitophagy using fluorescence lifetime imaging microscopy because excellent biocompatibility, photostability, specific recognition . This work not only demonstrates feasibility utilizing positional isomerization modulate excited‐state evolutions resultant optical properties, also provides evidence rationality constructing biologically‐active BioAIEgens via biomass‐derivatization concept.
