The metal organic framework CPM-5 (crystalline porous materials) was successfully synthesized and characterized for the first time using microwave irradiation as a rapid and facile synthesis method in about 10?min compared to several days crystallization time required for the conventional solvothermal approaches. Furthermore, CPM-5 produced by microwave-assisted synthesis exhibited a very high surface area of 2187?m2g1 compared to, e.g., 580?m2g1 of the conventionally synthesized samples. Moreover, the as-synthesized CPM-5 showed high carbon dioxide uptake.
