Perylene‐Grafted Silicas: Mechanistic Study and Applications in Heterogeneous Photoredox Catalysis

Carrillo, Adela I.; Elhage, Ayda; Marin, M. Luisa; Lanterna, Anabel E.

Abstract

A mechanistic study is herein presented for the use of heterogeneous photocatalysts based on perylene moieties. First, the successful immobilization of perylene diimides (PDI) on silica matrices is demonstrated, including their full characterization by means of electronic microscopy, surface area measurements, powder XRD, thermogravimetric analysis, and FTIR, 29Si and 13C solid‐state NMR, fluorescence, and diffuse reflectance spectroscopies. Then, the photoredox activity of the material was tested by using two model reactions, alkene oxidation and 4‐nitrobenzylbromide reduction, and mechanistic studies were performed. The mechanistic insights into their photoredox activity show they have promising dual photocatalytic activity for both organic oxidations and reductions.
