Cap in hand : Combined use of diamino‐γ‐cyclodextrin (CD) and Cu(ClO 4 ) 2 resulted in the first catalytic supramolecular photochirogenesis in the photocyclodimerization of 2‐anthracenecarboxylic acid. The anti ‐head‐to‐head cyclodimer formed in 64–70 % enantiomeric excess and about 50 % yield; these values are the highest ever reported for CD‐mediated photochirogenesis.
