Abstract

A robust, nano-sized covalent cage, of composition, [(PhSi)₆(ctc)₄]^6- (H₆ctc = cyclotricatechylene) has been prepared in a simple reaction in good yield. The tetrahedral anionic cage is stable in both the solid and solution state and exhibits an affinity for Cs⁺ ions which bind to the internal surface of the cage.
