Thiacrownophanes (6-8) wewre prepared by means of intramolecular photocycloaddition.Thiacrownophane (6) with two sulfur and three oxygen atoms showed the most efficient extractability toward Ag+ with high selectivity even if the extraction system did not contain any special lipophilic counter anion.
