Over the past decade, photoredox catalysis has rapidly developed and caught tremendous attention from synthetic chemists. Iridium and ruthenium polypyridyl complexes are among the most widely used and effective photo-redox catalysts (PCs). Yet their high cost, low sustainability, and potential toxicity are significant drawbacks. Organic dyes have been proven to be efficient alternatives, however, these can suffer from narrow redox window, pH-dependent. All widely used PCs are limited by the use of high energy light source. The goal of our project is to develop organic PCs that can be easily tuned, versatile, and utilized low energy light sources.
