Metal Organic Framework is a brand new crystalline porous materials with potential applications on gas storage, separation, catalysts and sensor. The focus of this work will be centered around the [N,N’-ethylenebis(salicyldeneaminato)] or also know as the salen ligand, It is a chiral ligand that is in this case Magnesium surrounded and stabilized by Oxygen and Nitrogen. This ligand is ideal due to the fact that it is easy to prepare, construct, and its versatile catalytic performance. Incorporation of a chiral Salen ligand into Metal-Organic Framework is a very promising method for obtaining heterogenous catalyst with high enantioselectivity for asymmetry reaction.
We’re active in developing the experimental conditions necessary for the formation of this Salen-MOF. This Salen-MOF will be prepared by using Terephthalic acid or Tetrakis(4-carboxyphenl)porphine as a plane and the ligand as its pillars to form the three dimensional structure. The experiments consist of modifying conditions to form the best quality crystalline structure suitable for single crystal diffraction examination as possible. Conditions used as variables include temperature, solvent, concentration of material, ligand, and pH value. I plan to use the newly synthesized MOF as catalyst to achieve high enantiosolectivity for asymmetric oxidation reactions.
This report will present the thus far promising results of the structure, properties, and characteristics of the completed salen-MOF as well as the data in acquiring high enantioselectivity using the MOF as a catalyst. The enantiomers will then by analyzed using High-performance liquid chromatography to determine the value of the difference between the amount of each enantiomer.
