Crownophanes possessing a pyridine moiety were prepared by means of intramolecular [2 + 2] photocycloaddition of the styrene derivatives. The crown compounds having six to ten ethereal oxygens selectively extracted Ag+ with high efficiency in the liquid-liquid extraction. The high extractability and efficiency were maintained even at low pH region of the extraction system. From ESI-MS analysis, it was found that the crownophanes formed some kinds of complexes having 1:1 and 2:1 stoichiometry (host/guest) with Ag+ and Pb2+ in MeCN-H2O homogeneous system.
