摘要：

Sandwiched: The cobaltabisdicarbollide (mono-)anion ([3,3′-Co(1,2- C2B9H11)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. © 2011 WILEY-VCH Verlag GmbH & Co.
