Surfactants are amphiphilic molecules that can form micellar structures with a hydrophobic core and a hydrophilic corona in water. In this work, we combine the remarkable properties of photoactive metal complexes with the supramolecular organization of surfactants to create photoactive vessels that support photocatalytic processes in aqueous media, even for starting materials that are insoluble in water. Herein, we report a library of photoactive metal complex surfactants (MeCSs) and their photophysical and photochemical properties. These properties are modulated by the length of an alkyl chain attached to the polypyridyl ligand of the metal complex. Finally, an alkene hydroxytrifluoromethylation photocatalytic reaction was demonstrated in aqueous solution, suggesting the usefulness of metal complex surfactants for the development of green aqueous photoreactions.
表面活性剂是两亲性分子，在水中可形成具有疏水核心和亲水冠层的胶束结构。在这项工作中，我们将光活性金属配合物的卓越性质与表面活性剂的超分子组织相结合，以创建光活性容器，该容器能在水性介质中支持光催化过程，即使对于不溶于水的起始原料也是如此。在此，我们报告了一系列光活性金属配合物表面活性剂（MeCSs）及其光物理和光化学性质。这些性质可通过连接到金属配合物多吡啶配体上的烷基链的长度来调节。最后，在水溶液中证明了烯烃羟基三氟甲基化光催化反应，这表明金属配合物表面活性剂对于开发绿色水性光反应具有实用性。
