A sensitive and visible fluorescence-turn-on probe for the CMC determination of ionic surfactants†
Abstract
A sensitive and visible fluorescence-turn-on probe for the critical micelle concentration (CMC) determination of ionic surfactants has been developed based on practically no emission in micelles but strong aggregation-induced emission in solution of racemate tetrahydropyrimide THP-1. CMC values were determined via the inflexion with the strongest fluorescence intensity.
