虽然通过水热或扩散方法制备特定的金属有机框架（MOF）材料通常需要数小时至数天，但我们简单的沉淀路线在几分钟内就可以获得众所周知的HKUST-1框架。对于形成定义明确的结晶材料至关重要的是选择合适的沉淀溶剂，其中甲醇和乙醇是最有利的溶剂。这种方法可以扩展到形成致密的表面安装的MOF膜（所谓的SURMOF），特别是如果表面通过形成自组装单层（SAMs）用合适的结合基团装饰。通过与微接触印刷（μCP）相结合，图案化的SURMOFs变得容易获得，其中沉淀溶剂对空间限制膜或单个颗粒的形成起决定性作用。
Whereas the preparation of defined metal–organic framework (MOF) materials via hydrothermal or diffusion methods typically requires hours to days, our simple precipitation route opens the access to the well‐known HKUST‐1 frameworks within minutes. Crucial for the formation of a well‐defined, crystalline material is the choice of suitable precipitating solvents, with methanol and ethanol being the most favorable ones. This approach could be extended to the formation of dense, surface‐mounted MOF films (so‐called SURMOFs), in particular if the surfaces are decorated with suitable binding groups by formation of self‐assembled monolayers (SAMs). By combination with micro‐contact printing (μCP), patterned SURMOFs became accessible, in which the precipitating solvent is decisive on the formation of either spatially restricted films or single particles.
