Chiral assembly of dodecahedral cavities into porous metal-organic frameworks

Corner-sharing assembly of dodecahedral cavities with both paddle-wheel [M-2(CO2)(4)] units and trimeric [M-3(mu(3)-OH)(CO2)(6)] units leads to two isomorphous chiral microporous metal-organic frameworks, where the heterometallic framework has high surface area and excellent CO2/N-2 adsorption selectivity.
