Main observation and conclusion Fluorescent intelligent materials have attracted wide attention because of their great potential applications. One major hurdle for the development and application of fluorescent intelligent materials is the aggregation‐caused quenching effect in the solid state. Herein, tetraphenylethylene‐based trithiocarbonate polymers with satisfactory molecular weights ( M w up to 24900) were synthesized through a one‐pot polymerization route under mild conditions. The polymers were non‐emissive due to the quenching effect of the trithiocarbonate group. However, upon UV irradiation, the polymers degraded and strong emission from the tetraphenylethylene unit was observed. Such a unique property endows them with great potential applications, such as photopatterning, anti‐counterfeit labels, and UV detection.
