Abstract

In this study, a series of surfactants containing fluorescein, alkyl fragments, and a polar imidazolium polar group were synthesized. The aggregation properties of the compounds in aqueous buffer solutions were studied using fluorescence and Nanoparticle Tracking Analysis (NTA), which allowed the critical micelle concentration and the size of the associates to be determined, respectively. The quantum yields of the obtained surfactants were determined by a relative method. It was demonstrated that the surfactant containing an octyl fragment exhibits a high quantum yield of up to 78%.
