The use of supramolecular interactions to control and direct excited-state reactivity is described, with emphasis on the author's contributions in this area. The systems are based on the multiple-point hydrogen-bonding molecular recognition motif present in the melamine–barbituric acid system, and are designed to operate in solution phase. Despite the weak nature of non-covalent interactions, control of high energy intermediates such as excited cinnamantes, stilbenes, or fullerenes is possible. These results demonstrate the particular sensitivity of short-lived electronically excited molecules to their environment, and particularly to the mutual orientation of the reactants.
