Uniform, Binary Functionalization of a Metal-Organic Framework Material.

General routes to confined spaces of well-defined chemical composition and complex three-dimensional structure have long been sought by materials chemists. Here, we introduce metal-organic framework (MOF) materials as an ideal scaffold upon which such organized complexity can be built. Employing an orthogonal coordination strategy, we constructed a large-pore MOF material with two different modifiable linkers in well-defined positions relative to each other. The
