Rose Bengal Immobilized on Cellulose Paper for Sustainable Visible-Light Photocatalysis.

This work reports the heterogenization of Rose Bengal dye on simple cellulose paper sheets (Cell-RB) through copper-catalyzed azide-alkyne click ligation. The photocatalytic properties of Cell-RB under green LED irradiation were evaluated in a series of dehydrogenative transformations for the functionalization of N-aryltetrahydroisoquinolines and quinoxalin-2(1H)-ones. The excellent photocatalytic activities observed, associated to the ease of recovery with simple tweezers, highlight the strong assets of Cell-RB with respect to traditional homogeneous organic photocatalysts. © 2022 The Authors.
