説明
<jats:p> Although zeolites and related materials combine nanoporosity with high thermal stability, they are difficult to modify or derivatize in a systematic way. A highly porous metal coordination polymer [Cu <jats:sub>3</jats:sub> (TMA) <jats:sub>2</jats:sub> (H <jats:sub>2</jats:sub> O) <jats:sub>3</jats:sub> ] <jats:sub> <jats:italic>n</jats:italic> </jats:sub> (where TMA is benzene-1,3,5-tricarboxylate) was formed in 80 percent yield. It has interconnected [Cu <jats:sub>2</jats:sub> (O <jats:sub>2</jats:sub> CR) <jats:sub>4</jats:sub> ] units (where R is an aromatic ring), which create a three-dimensional system of channels with a pore size of 1 nanometer and an accessible porosity of about 40 percent in the solid. Unlike zeolites, the channel linings can be chemically functionalized; for example, the aqua ligands can be replaced by pyridines. Thermal gravimetric analysis and high-temperature single-crystal diffractometry indicate that the framework is stable up to 240°C. </jats:p>
