Sandwiched : The cobaltabisdicarbollide (mono‐)anion ([3,3′‐Co(1,2‐C 2 B 9 H 11 ) 2 ] − , COSAN − ) forms monolayer vesicles at low concentrations in water (see picture). An increase in concentration leads to a Coulomb explosion of the closely packed vesicles into small micelles, which results in the coexistence of both aggregation states at higher concentrations.
