The protolytic and complexing properties of phosphorylated derivatives of calix[4]resorcinolarenes were studied by pH-metric titration at 298 K in water-2-propanol (80 vol % 2-propanol). It was shown that calix[4] resorcinolarene containing the propylphosphonic acid fragment at the C atom linking the aryl groups exists in solution mainly as tetramer. At pH > 4, the anions of tetrameric, dimeric, and monomeric forms of this compound are formed. The neutral form of aminomethylated calix[4]resorcinolarene contaning, along with the propylphosphonic acid fragment, the CH2NEt2 group on the opposite side of the molecule is monomeric. It exists as a zwitterion and contains four betaine protons. Three dimeric species of this compound, one protonated...
