A quaterthiophene-based boron dipyrromethene (Bodipy) dyad when dispersed uniformally in silicone rubber produces a thermoresponsive fluorescent material. The yellow fluorescence colour observed at low temperatures <200 °C changes to green upon heating the polymer. In contrast, the phenylene-based Bodipy dyad in silicone rubber displays a partial on to off fluorescence change at around 70 °C.
