摘要：

Both NMR spectra in nitrobenzene-d (5) and high-precision quantum mechanical DFT calculations proved that tetramethyl p-tert-butylcalix[4]arene tetraketone binds hydroxonium cation H(3)O(+) quite strongly to form an equimolar complex. Three different structures of the resulting complex species were indicated by the NMR spectra and the DFT calculations.
