Abstract Cross‐responsive chemical sensors are in high demand owing to their ability distinguish a broad range of analytes. In this study, vapochromic sensor array based on metal–organic frameworks (MOFs), which exhibits distinct patterns when exposed volatile organic compounds (VOCs) and humidity, is developed. Conventional arrays consist various receptors that produce different responses. The MOF‐based comprises dicopper paddlewheel clusters dimethylamine azobenzene as binary colorimetric sensing moieties. Upon exposure VOCs, the constructed encompasses spectrum colors, ranging from green red. Furthermore, color MOF influenced by solvent used during pretreatment. Consequently, monolayered thin films can be adapted multicomponent systems immersing solvents. This system provides both qualitative quantitative sensing, generating unique corresponding specific VOC types. Notably, successfully discriminates each 14 common VOCs water accurately categorizes unknown samples. Moreover, undergoes reversible changes response obviating need for high‐temperature regeneration steps. novel approach offers insights into versatile applications MOFs creating capable detecting
