Abstract

A simple and novel method is proposed here for the first time to determine pK_a values of chromogenic hydrophobic pH sensitive probes directly in nanospheres. pK_a values can be obtained by measuring the pH response of the nanospheres (containing the probes and ion exchanger) followed by measuring the pH and Na⁺ responses of the nanospheres (containing solvatochromic dyes and ion exchanger). The pK_a values of four chromoionophores were successfully determined. This method is in principle also applicable to characterize colorimetric probes in other water immiscible nanomaterials. (Figure Presented).
