虽然沸石和相关材料联合收割机结合了纳米孔隙率和高热稳定性，但它们难以以系统的方式改性或衍生化。以80%的产率形成高度多孔的金属配位聚合物[Cu-3（TMA）（2）（H2O）（3）]（n）（其中TMA是苯-1，3，5-三羧酸酯）。它具有相互连接的[Cu-2（O2 CR）（4）]单元（其中R是芳香环），其产生具有1纳米孔径和固体中约40%的可接近孔隙率的三维通道系统。与沸石不同，通道衬里可以化学官能化;例如，水配体可以被吡啶取代。热重分析和高温单晶衍射表明，该框架是稳定的高达240 ℃。
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-3(TMA)(2)(H2O)(3)](n) (where TMA is benzene-1,3,5-tricarboxylate) was formed in 80 percent yield. It has interconnected [Cu-2(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 degrees C.
