Title:
INORGANIC MESOPOROUS SUBSTANCE HAVING CHIRAL TWISTED STRUCTURE AND PROCESS FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2005/105672
Kind Code:
A1
Abstract:
A chiral inorganic mesoporous substance characterized by having a chiral twisted structure and being mesoporous; a process for producing the substance; and a method of using the substance. The process for inorganic mesoporous substance production is a method in which one or more polymerizable inorganic monomers selected from the group consisting of polymerizable inorganic monomers and polymerizable inorganic monomers having a functional group capable of having a charge are polymerized in the presence of a solvent using as a template a self-assembly of a chiral surfactant such as an N-(higher alkanoyl)amino acid salt. Examples of the use of the inorganic mesoporous substance include the separation of racemates and reaction fields for asymmetric syntheses.
