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

用于快速切换酸性传感的绿光介导单分子平台的合理设计

可控的感测能力与诊断和治疗中的复杂而精确的事件密切相关。然而，由于缺乏结构上的相关性，将可见光强加于传感过程的分子尺度介导中。为了解决这一关键挑战，我们提出了一种新颖的氰基苯乙烯基改性的z基体系的合理设计，合成和体外研究，用于绿光介导的快速可切换酸性传感。设计的优势包括高效的绿光驱动Z / E-异构化（量子产率高达61.3％），可快速消除色度和发光表达，并与比例质子化控制具有出色的兼容性。重要的是，设计的这些优点使得微流体系统的开发能够在微型化平台中对胃酸分析物执行绿光介导的可重复使用的传感功能。结果可能为构建未来的集成绿色材料提供新的见解。
