Description
`There is currently a huge appeal for “chemosensors” based on metal−organic frameworks (MOFs) for the sensitive and selective detection of gas- and vapor-phase analytes for a range of applications including chemical threat alerts, medical diagnostics, and environmental monitoring. Here, We have developed a simple colorimetric molecular sensor that detects a wide range of volatile analytes and then applied it to the detection of toxic gases. The sensor consists of a mononuclear complex, [Fe(trz-tet)$_2$(H$_2$O)$_4$]$\cdot$2H$_2$O, with a FeN$_2$O$_4$ chromophore with monodentate triazole coordination that can be changed by diverse chemical interactions with analytes. The colour change for the sensor is a unique molecular fingerprint. Clear differentiation among 6 different chemicals, including 4 toxic industrial chemicals (TICs) within two minutes of exposure under vapor diffusion.`
