Determination of critical micelle concentration of dendritic surfactant synthesized via a selective ring-opening addition reaction

► Dendrons with terminal C4 groups were synthesized from an azetidine-2,4-dione. ► By acidification, a dendritic surfactant was subsequently obtained. ► Its CMC was determined by fluorescence and conductivity measurements. ► The resulted CMC values were very close within measurements, ca. 0.013-0.05 mM. ► Anionic dyes were adsorbed onto the dendritic surfactant micelles successfully.
