[ДСТУ] Study of Calixarene Complexation with Biologically Active / O. Kalchenko et al. French-Ukrainian Journal of Chemistry. 2017. Vol. 5, no. 2. P. 49—55. DOI: 10.17721/fujcV5I2P49-55 (date of access: 25.07.2026).
Host-Guest complexation of octakis(diphenoxyphosphoryloxy)tetramethylcalix[4]resorcinarene CRA and 5,17-bis-(N-tolyliminomethyl)-25,27-dipropoxycalix[4]arene CA with bio relevant aromatic, pyridine and diterpenoid carboxylic acids in water-organic solution had been studied by the RP HPLC and molecular modelling methods. The stability constants KA (387-1914 М-1) of the supramolecular complexes had been determined. It was shown the Host-Guest interactions are depended on structure of the Host molecules and log P values of the Guests. The complexation is determined by the hydrogen bonds of the COOH group of the carboxylic acids with P=O oxygen atom of diphenoxyphosphoryl group of the calixresorcinarene CRA, and oxygen or nitrogen atoms located on the lower or the upper rim of the calixarene CA.
