The raising apprehension of volatile organic compound (VOC) exposures urges the exploration of advanced monitoring platforms. Metal–organic frameworks (MOFs) provide many attractive features including tailorable porosity, high surface areas, good chemical/thermal stability, and various host–guest interactions, making them appealing candidates for VOC capture and sensing. To comprehensively exploit the potential of MOFs as sensing materials, great efforts have been dedicated to the shaping and patterning of MOFs for next-level device integration. Among different types of sensors (chemiresistive sensors, gravimetric sensors, optical sensors, etc.), MOFs coupled with optical sensors feature distinctive strength. This review summarized the latest advancements in MOF-based optical sensors with a particular focus on VOC sensing. The subject is discussed by different mechanisms: colorimetry, luminescence, and sensors based on optical index modulations. Critical analysis for each system highlighting practical aspects was also deliberated.

用于VOC传感的基于MOF的光学传感器的最新进展

对挥发性有机化合物 (VOC) 暴露的日益担忧促使人们探索先进的监测平台。金属有机框架 (MOF) 具有许多吸引人的特性，包括可定制的孔隙率、高表面积、良好的化学/热稳定性以及各种主客体相互作用，使它们成为 VOC 捕获和传感的有吸引力的候选材料。为了全面挖掘 MOF 作为传感材料的潜力，人们一直致力于 MOF 的成形和图案化，以实现下一级器件集成。在不同类型的传感器中（化学电阻传感器、重力传感器、光学传感器等）。), MOFs 与光学传感器相结合具有独特的优势。本综述总结了基于 MOF 的光学传感器的最新进展，特别关注 VOC 传感。该主题通过不同的机制进行讨论：比色法、发光和基于光学指数调制的传感器。还审议了针对每个突出实际方面的系统的批判性分析。
