An international team of researchers (Spain, France, USA – Lawrence Berkeley National Laboratory) proposes the use of a simple non-porous coordination polymer that shows a magneto-structural transition under desorption/absorption of acetonitrile molecules in the structure. This reversible change produces a measurable response in the presence of acetonitrile. This response comes in the form of a change in the color of the polymer from orange to yellow and an abrupt increase in the electrical conductivity. Both responses are easily observed by the naked eye or easily measured, providing an obvious advantage over other costly analytical techniques. The responses occur at well-defined temperatures close to ambient conditions…read more. Open Access TECHNICAL ARTICLEÂ
