Intrinsic triple-emitting 2D copper thiolate coordination polymer as a ratiometric thermometer working over 400 K range†
Abstract
A copper thiolate coordination polymer, [Cu(p-SPhCO2Me)]n, is described and exhibits, under UV, luminescence thermochromism, associated to a unique well-separated triple emission. This compound is the most promising candidate as a ratiometric temperature sensor, working in a wide temperature range, from 100 to 500 K, with a great sensitivity.
