%X Thermoresponsive polymers that undergo a solubility transition by variation of the temperature are important materials for the development of ˇ®smartˇŻ materials. In this contribution we exploit the solubility phase transition of poly(methoxy diethylene glycol methacrylate), which is accompanied by a transition from hydrophilic to hydrophobic, for the development of a fluorescent thermometer. To translate the polymer phase transition into a fluorescent response, the polymer was functionalized with pyrene resulting in a change of the emission based on the microenvironment. This approach led to a soluble polymeric fluorescent thermometer with a temperature range from 11 ˇăC to 21 ˇăC. The polymer phase transition that occurs during sensing is studied in detail by dynamic light scattering.
