dc.description.abstract | A photoinduced charge transfer (PCT)-based 1,3-alternate calix[4]crown fluoroionophore containing two cation recognition sites, a crown ether ring and two facing pyreneamide groups, is synthesized. Upon addition of K +, Pb 2+, or Cu 2+, wavelength changes are observed in both the fluorescence and absorption spectra, but with different binding modes. With K +, fluorescence emissions of the ligand scarcely change, while addition of Pb 2+ or Cu 2+ produces a remarkable change in both the excimer and monomer emissions. The observed data indicate that the metal cation is encapsulated in the crown-5 ring for K + and by the two facing amide groups in the latter case, which is verified by a metal ion exchange experiment. The wavelength shifts in both fluorescence and absorption spectra upon addition of Cu2+ show that, in contrast to Pb 2+, Cu 2+ interacts with the nitrogen atoms of the amide groups, resulting in a PCT mechanism. © 2006 American Chemical Society. | * |
