Spiropyran-conjugated thermoresponsive copolymer as a colorimetric thermometer with linear and reversible color change.
A simple copolymer, poly(NIPAM-co-SP), consisting of N-isopropylacrylamide and spiropyran units, behaves as a colorimetric thermometer exhibiting temperature-responsive linear and reversible bathochromic/hypsochromic shift of the absorption spectra under UV irradiation.
