✦ Synopsis

Geminate radical pairs are formed from the a-photocleavage of aryl ketones within the supercage of zeolites which has been modified with chiral guest molecules. Herein, we report the supramolecular structure and dynamic control of both the enantiomeric selectivity and probability of the recombination of the radical pairs.
