Recently, various metal organic frameworks (MOFs), which are 3-D network coordination polymers, have been explored to obtain porous materials having homogeneous pore size, various pore shape, and high surface area. MOFs have been synthesized by reaction metal and organic ligands of mainly the types of dicarboxylate or bipyridine derivatives. However, most of them have been prepared under severe conditions such as high temperature (over 200 oC), high pressure, and long preparation time. Thus, in this presentation, it was aimed at finding the mild synthetic conditions to prepare highly crystalline MOFs based on titanium and aromatic diol systems. Physicochemical structure and pore characteristics of MOFs was characterized by the FTIR, elemental analysis, SAXS, XRD, and nitrogen adsorption instrument. |
