A controllable sensing ability strongly connects to complex and precise events in diagnosis treatment. However, imposing visible light into the molecular-scale mediation of processes is restricted by lack structural relevance. To address this critical challenge, we present rational design, synthesis, vitro studies a novel cyanostyryl-modified azulene system for green-light-mediated fast switchable acidic sensing. The advantageous features design include highly efficient green-light-driven Z/E-isomerization (a quantum yield up 61.3%) erasing chromatic luminescent expressions superior compatibility with control ratiometric protonation. Significantly, these merits enable development microfluidic perform reusable function toward gastric acid analyte miniaturized platform. results may provide new insights building future integrated green materials.
