The ability of γ-cyclodextrin to form ternary inclusion complexes has been utilized to mediate photo-heterodimerization between cinnamic acids and coumarins in the solid-state. Stabilizing steric and electronic interactions between the alkenes in the inclusion complex appear to be primarily responsible for directing the complexation toward the 1:1:1 hetero-guest pair complex. Photoexcitation of the
