Chiral assembly of dodecahedral cavities into porous metal-organic frameworks.

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

Charge matching on designing neutral cadmium-lanthanide-organic open frameworks for luminescence sensing.

Through careful consideration of charge matching, a simple replacement of metal ion from Cd(2+) to Ln(3+) in a building unit successfully transforms an anionic microporous framework into a series of isostructural porous neutral heterometallic frameworks [Cd(3)Ln(2)(btc)(4)(H(2)O)(6)(dmf)(4)]·x(solvent) (1; Ln=Tb, Eu, Nd, Gd, Sm, dmf=N,N'-dimethylformamide) by employing five different lanthanide ions. 1-Tb and 1-Eu exhibit interesting photoluminescent properties, and remarkably, 1-Tb can act as a luminescent sensor to identify organic solvents and metal ions.

A microporous indium-organic framework with high capacity and selectivity for CO2 or organosulfurs.

Presented here is a multifunctional microporous indium-organic framework material with doubly linked MIL-88D structure, which exhibits high surface area, excellent CO(2)/N(2) adsorption selectivity, good hydrogen storage ability and notable desulfurization behavior.
