Gaynanova G. A. Pyrene fluorescence quenching in supramolecular systems based on dimethylaminomethylated resorcinarene / G. A. Gaynanova, A. M. Bekmukhametova, R. K. Mukhitova, S. V. Kharlamov, A. Y. Ziganshina, L. Ya. Zakharova, A. I. Konovalov // J. Mol. Liq. -2015. – 206. – C. 316-320.

Annotation

The aim of this work is the development of stable fluorophore-quencher pairs with a controlled response for bioassay in the laboratory. The widely used in bioanalysis pyrene and its water-soluble derivative were selected as organic fluorophores. Water-soluble aminomethylated calixarene with sulfonatoethyl groups at the “lower rim” was chosen as a stabilizer. We have established a strong fluorescence quenching in the solution of resorcinarene even at low premicellar concentrations which indicates the pyrene transition into a non-polar microenvironment. The data on the influence of pH, buffer composition, and the macrocyclic platform on the fluorescence quenching of pyrene in the presence of resorcinarene were obtained. The temperature dependence of the fluorescence quenching of pyrene was obtained with the aim of establishing the mechanism of the formation of complex fluorophore-resorcinarene (static versus dynamic quenching).
