Colloidal Metal Chalcogenide Quantum Dots as Photo-Redox Catalysts for Model Reactions Relevant to the Formation of Liquid Fuels
Abstract
Our work on this project focused on quantum dot (QD)-photocatalyzed chemoselective and stereoselective organic reactions, namely demonstrating how adsorption of molecules to the surface of QDs can be used to provide microenvironments that promote enhanced photophysical processes and enhanced selectivity of chemical reactions. We show that colloidal QDs serve as visible-light chromophores, photocatalysts, and reusable scaffolds for homo- and hetero-intermolecular [2 plus 2] photocycloadditions of unprecedented regioselectivity and diastereoselectivity for the previously minor syn-cyclobutane products, including the synhead-to-tail cyclobutane, which has never before been accessed as the major product of a heterophotocycloaddition. This work produced series of pioneering, high-impact publications that provide fundamentally new strategies for challenging organic reactions.
