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 [Cu3(TMA)2(H2O)3]n (where TMA is benzene-1,3,5-tricarboxylate) was formed in 80 percent yield. It has interconnected [Cu2(O2CR)4] 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 degreesC.

可化学官能化的纳米多孔材料

尽管沸石和相关材料将纳米多孔性与高热稳定性结合在一起，但它们很难以系统的方式进行修饰或衍生。以80％的收率形成了高度多孔的金属配位聚合物[Cu3（TMA）2（H2O）3] n（其中TMA为1,3,5-三羧酸苯）。它具有相互连接的[Cu2（O2CR）4]单元（其中R是芳环），形成了三维系统的通道，其孔径为1纳米，固体中的孔隙率约为40％。与沸石不同，通道衬里可以进行化学功能化。例如，水配体可以被吡啶取代。热重分析和高温单晶衍射分析表明，该框架在高达240℃的温度下仍保持稳定。
