The structures of ionophore 6-O-bpy 1 and 1-Cu+ complex were studied by 500 MHz 1H nmr spectrometry. Characteristic downfield and upfield shifts of the aromatic
protons, and the methyl and the methylene protons in the picolyl moiety support strongly generation of pseudocrown structure in the 1-Cu+ complex.
