Abstract
Disclosed herein are methods in which colloidal quantum dots (QDs) can serve as visible-light chromophores, photocatalysts, and reusable scaffolds for homo- and hetero-intermolecular [2+2] photocycloadditions. The methods may lead to >90% tunable regioselectivity and up to 98% diastereoselectivity for previously minor syn-cyclobutane products, including the syn-head-to-tail cyclobutane.
