摘要：

Efficient and low cost detection of harmful volatile organic compounds ( VOCs) is a major health and environmental need in industrialized societies. For this, tailor- made porous coordination polymers are emerging as promising molecular sensing materials thanks to their responsivity to a wide variety of external stimuli and could be used to complement conventional sensors. Here, a non- porous crystalline 1D Fe( II) coordination polymer acting as a porous acetonitrile host is presented. The desorption of interstitial acetonitrile is accompanied by magneto- structural transitions easily detectable in the optical and electronic properties of the material. This structural switch and therefore its ( opto) electronic readout are reversible under exposure of the crystal to acetonitrile vapor. This simple and robust iron- based coordination polymer could be ideally suited for the construction of multifunctional sensor devices for volatile acetonitrile and potentially for other organic compounds.
