Abstract

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.
