Abstract Stability constants of the host–guest complexes of octakis(diethoxyphosphoryloxy) tetramethylcalix[4]resorcinarene (RA) with different benzene derivatives (alkyl benzenes, halogenated benzenes, substituted aldehydes, phenols and benzoic acids) were determined by the reversed phase high-performance liquid chromatography (RP HPLC) method (Separon SGX C 18, UV detector at 254 nm and acetonitrile-water, 86 : 14, v/v, as mobile phase) from the relationship between the aromatic guest capacity factors and the RA host concentration in the mobile phase. The constants are within the range 17–596 M−1, dependent on the size, nature, position and quantity of the substituents in the benzene ring of the guest molecules.
