A chameleon luminophore : A temperature‐sensing material is reported that has a high thermostability (see picture). The material is composed of color‐changing luminescent coordination polymers containing Eu III and Tb III ions. The coordination polymer exhibits a high emission quantum yield Φ of 40 % at room temperature and a temperature‐sensing ability over a wide range of 200–500 K.
