γ-cyclodextrin; FRET sensitization; photochirogenesis; photocyclodimerization; Introduction
Chiral photochemistry, often characterized by low optical yields, remains a great challenge for chemists [1][2][3]. This situation reflects primarily the difficulty in efficiently transferring the
within the CD cavity, minimizing the “contamination” from the achiral “outside” photoreaction, is responsible. FRET sensitization also enabled us to achieve the catalytic photocyclodimerization of AC with a sub-equivalent amount of chiral supramolecular host.
