Abstract:

Metal Organic Frameworks (MOFs) are frameworks of 1-3D formed by the interaction between organic molecules and metal ions/clusters. The high specific surface area (~1000-5000 m2 g-1) and large pore volume (~0.7-2.5 cc g-1) of these molecules render them as ideal candidates for catalysis, gas absorption, separation of gases and sensing applications. The pore size and surface area can be tailored by modifying the synthetic conditions. In this paper, we report the synthesis and characterization of MOF-199 for potential application in enzyme-based sensing. MOF-199 was synthesized under room temperature using benzenetricarboxylic acid and a 1:1:1 mixture of DMF/ethanol/copper (II) acetate. Further, triethylamine (0.5 mL) was added to the reaction mixture and the resultant mixture was stirred for 23 h followed by drying to obtain a bluish crystalline material of MOF-199. The crystalline material was characterized using various analytical and microscopic techniques.
