INFLUENCE OF COMPONENT PROPORTIONS OF MICELLAR SOLUTIONS ON THE SPECTRAL PROPERTIES AND SOLUBILIZATION BY PLURONIC OF A BORONDIFLUORIDE DIPYRROMETHENE DERIVATIVE
Abstract
It has been shown by a spectral method that the efficiency of solubilization of a borondifluoride dipyrromethene derivative by Pluronic F-127 inmixed systems depends on the proportions of mass concentrations of the dye and Pluronic in an initial liquid solution. It has been established that the values of the Pluronic F-127 concentration, at which the micelles solubilizing the dye are efficiently formed, exceed 10 % (mass). The analysis of spectral characteristics of the solution of the “dye – Pluronic” adducts has shown that the dye under study exists in the Pluronic micelles in the highest degree of disaggregation manifesting the spectral characteristics of monomeric form.
