A microporous metal-organic framework (MOF) was synthesized from [Zr6O4(OH)(4)(C6H5COO)(12)] clusters and a triacid ligand based on a shape-persistent arylene ethynylene macrocycle. This framework, dubbed Zr-MCMOF, is held together by metal-ligand coordination and multiple weak interactions: hydrogen bonding, [pi center dot center dot center dot pi] stacking, and [C H center dot center dot center dot pi] interactions. The rigid ligand has a 9 angstrom-wide central void, which serves as a predesigned aperture for the 1D channels; all of the porosity of Zr-MCMOF comes from the ligand. The resulting framework possesses high hydrolytic and thermal stability and a flexible structure unique among Zr-based MOFs.
