p-tert-Butylcalix[4]arene 1,3-digallate, which contains a nonbonded close contact between galloyl groups, was synthesized and its structure was determined by dynamic (1)H NMR and X-ray crystallography. The electronicspectra showed that a new absorption band of the complexes appeared at a longer wavelength region upon adding Ag(+) ion. This spectral shift was explained in terms of the interactionbetween the facing
