The Study On Performance Of In-azo MOFs Catalyzed Knoevenagel Condensation And Light Control

Metal-organic frameworks（MOFs） are composed of inorganic metal ions and organic ligands by coordination bond to form a new-type porous material, and has a great surface, high porosity,the chemical structure. MOFs have a broad application prospect in optical, magnetic,gas adsorption/separation and heterogeneous catalysis. But in the catalytic properties of lighe regulation there are still gaps. This paper studies the catalytic properties of the new In-azo MOFs that azobenzene-4,4’-dicarboxylic acid as a ligand and InC_l3·6H₂O providing center ions by hydrothermal method successfully synthesized. We have verified the catalytic properties in the Knoevenagel condensation reaction. The contents are divided into the following three parts:1. In this work, we synthesize the In-azo MOFs and its structure, thermal stability and fluorescence properties were characterized by infrared analysis, X-ray single crystal diffraction analysis, various functional chemical related were studied.2. Catalytic of In-azo MOFs for Knoevenagel condensation reaction. In-azo MOFs can catalyze the Knoevenagel condensation reaction effectively in a polar solvent such as ethanol. We also study the mechanism of In-azo MOFs catalyze the Knoevenagel condensation reaction.3. Prelimary exploration of the In-azo MOFs properties of light-control study.
