Photoflow production of mercaptosilane-armored rose bengal for organodisulfide synthesis

Abstract

We have developed a facile flow system to encapsulate photosensitizers (rose bengal) in the silica matrix via photocrosslinking to form redox-responsive silica nanocomposites pf-ReSiNPs with a throughput > one order of magnitude than that of batch synthesis. The organodisulfide synthesis via pf-ReSiNPs effectively addresses the issues of photobleaching, purification, and environmental impact, typically seen using photosensitizers as catalysts in reactions.
