Abstract
The present invention discloses chiral siliceous composition comprising chiral or achiral silane moiety 'A', substituted in another moiety 'B' with tetrahedral metallo-silica or silica framework with mesoporous and microporous structure, useful as chiral heterogeneous catalyst and in enantioselective separations. The invention further discloses a method for introducing molecular level chirality in crystalline framework of silicate and metallosilicate with mesoporous or microporous structure thereof.
