Abstract

A versatile strategy for smart fluorescent materials is lacking due to their diverse responding mechanisms and incompatibility of responsive behaviors. Herein an adaptable strategy is presented toward a multi-stimuli-responsive fluorescent material with stage-by-stage responsive behavior by blending linear polymers modified with different stimulus-responsive moieties and AIE cross-linker. Under stimuli, the linear polymer can cross-link with the cross-linker to form networks, which intrinsically restrict the intramolecular rotation of the AIE molecule to induce strong emission. A unified stimuli-responsive mechanism is involved in that various stimuli are transferred through the organized “stimulus-crosslink-emission” process. This strategy ensures the compatibility of different stimuli-responses and the adjustability of stimulus-response behavioral logic. These multi-stimuli-responsive fluorescent materials exhibited strong accessibility and adaptability for information encryption.
