"Protonated tetramethyl p-tert-butylcalix[4]arene tetraketone: NMR evidence and probable structures" . "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 H3O+ 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."@en . . "Dybal, Ji\u0159\u00ED" .
