| Abstract: | This article is a highlight of the paper by Ferrari et al. in this issue of Photochemistry and Photobiology. It describes the innovative use of rose bengal‐conjugated chitosan as a reusable green catalyst that photo‐degrades phenolic compounds in aqueous media, and thereby has decontamination potential of polluted waters. Whether a next‐generation photoactive polymer that produces singlet oxygen is a solution to pollutant degradation can be argued. It is as yet unclear what polymeric sensitizer would be practical on a large scale. Nonetheless pursuing this goal is worthwhile. |
