Folding of hydrocarbon chains and reduction in micelle size are observed as the number of headgroups ( h ) on the new single‐chain cationic surfactants increases from ( h = 1) to bident ( h = 2) or trident ( h = 3, see picture). The aggregation number is dramatically decreased and the fractional charge on the micelle increases with the increase in the charge at the headgroup.
