The idea behind the sol-gel synthesis methodology is to “dissolve” a compound in a liquid in order to bring it back as a solid in a controlled manner. Though this method, multi component compounds can be prepared in a controlled stoichiometry leading to the formation of an oxide network through polycondensation reactions from a molecular precursor dissolved in a solution. Thus, the sol-gel method for inorganic synthesis prevents problems such as (a) co-precipitation, which may be inhomogeneous and caused gelation reaction, and (b) it enables mixing at an atomic level, which results in small particles that are easily sinterable. In addition, the method allows prepare materials with a variety of shapes, such as porous structures, thin fibers, dense powders and thin films. The explosion and interest in hybrid inorganic/organic framework materials containing carboxylates and phosphonate ligands, has been driven by both the diversity of structural and chemical types and the possible applications of these hybrid framework materials in areas such as catalysis, separations, hydrogen storage, and electrical conductivity. An attractive strategy for the synthesis of these networks is through the reaction of main group metal salts such as magnesium, calcium, and barium under the presence of di topic carboxylate and phosphate ligands. We have sought to extend our work in this area towards an ease formation of sol gel matrix to growth homochiral inorganic frameworks, which can be used in enantio selective separations as well in homogeneous or heterogeneous asymmetric syntheses. Long ago, we have choice to study the use of dicarboxylate L-tartrate (L-tart = C4H4O6) and HPO4-2 ligands towards a feasible sol gel framework synthesis.
