Aqueous Self-Assembly and Cation Selectivity of Cobaltabisdicarbollide Dianionic Dumbbells

Original language description

The anion [3,3'-Co(C2B9H11)2]- ([COSAN])- produces aggregates in water. These aggregates are interpreted to be the result of C-H...H-B interactions. It is possible to generate aggregates even after the incorporation of additional functional groups into the [COSAN]- units. The approach is to join two [COSAN]- anions by a linker that can adapt itself to act as a crown ether. The linker has been chosen to have six oxygen atoms, which is the ideal number for K + selectivity in crown ethers. The linker bindsthe alkaline metal ions with different affinities; thus showing a distinct degree of selectivity. The highest affinity is shown towards K + from a mixture containing Li+,Na+,K +,Rb+and Cs+; this can be indicative of pseudo-crown ether performance of thedumbbell. One interesting possibility is that the [COSAN]- anions at the two ends of the linker can act as a hook-and-loop fastener to close the ring. This facet is intriguing and deserves further consideration for possible applications.
