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 recombinatio

## Abstract The photolysis of (R)‐(+)‐phenyl and (R)‐(+)‐__p__‐anisyl 1, 2, 3‐trimethylcyclopent‐2‐enyl ketone (**1**, **2**) and the corresponding __rac__‐1‐ and 3‐desmethyl analogs (**3**, **4**) led to isomerization due to formal 1, 3 aroyl migration and to formation of aryl aldehydes (**7**, **
