Abstract
The self‐assembly of metallacarboranes, a peculiar family of compounds exhibiting surface activity and resembling molecular‐scale Pickering stabilizers, has been investigated by comparison to the micellization of sodium dodecylsulfate (SDS). These studies have shown that molecules without classical amphiphilic topology but with an inherent amphiphilic nature can behave similarly to classical surfactants. As shown by NMR techniques, the self‐assembly of both metallacarboranes and SDS obey a closed association model. However, the aggregation of metallacarboranes is found to be enthalpy‐driven, which is very unusual for classical surfactants. Possible explanations of this fact are outlined.
