Morozova Ju. E. Investigation of Tetramethylenesulfonated Calix[4]Resorcinarene Interactions with Azo-Dyes in Aqueous Solution. / Morozova Ju. E., Kazakova E. Kh., Mironova D. A., Shalaeva Ya. V., Syakaev V. V., Makarova N. A., Konovalov A. I. // J. Phys. Chem. B. - 2010. - V.114, No. 41. - P. 13152–13158. |
Аннотация |
Here, we report on the interactions of nonaggregated methyl-substituted (SCA1) and aggregated penthyl-substituted (SCA2) tetramethylenesulfonated calix[4]resorcinarenes with pH indicators methyl yellow (MY) and methyl orange (MO) in aqueous solutions. It was found that the pH of aqueous solutions of SCA1 and SCA2 depends on their concentration; besides, variation of the concentration of SCA1 and SCA2 results in a shift of the absorption maxima and of pH-sensitive azo dyes. Association of the marocycles with azo dyes was demonstrated to follow a proton-transfer mechanism accompanied by protonation of the dyes; it was found that excess of the macrocycle in solution with the universal buffer background shifts the pKa values and stabilizes the protonated form of the dyes. |
