Photocatalytic functionalization of thin-layer membranes using a monomer truncation strategy

Abstract

We present the design and synthesis of two new organic polymer films making use of a liquid–liquid interfacial amine–acid chloride polymerization strategy. One of them was additionally functionalized in situ by the anchoring of N-phenyl-phenothiazine through a monomer truncation strategy, which endowed it with photocatalytic activity. This photoactive film displays interesting luminescence phenomena that were used for the oxidation of a variety of sulphides to their corresponding sulfoxides and reduction of aryl bromines.
