Molecular sensors that allow monitoring of mechanical deformation or exposure to extreme temperatures could be facilitated by exploiting the variation of the emission color of blends of a host polymer and a low‐molecular‐weight photoluminescent dye. Due to excimer formation, the emission color (see Figure) strongly depends on the extent of aggregation of the sensor molecules, which is affected by the stimulus to be sensed.
