TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The material has ordered pore structure with pores of 1-10 nm. The material has a hexagonal, arrangement of pores. The ordered pore structure has 2-dimensionally or 3-dimensionally connected pores. The material is a metal oxide and/or a carbon mesoporous material and the template has been removed either through calcination or through solvent extraction. The mesoporous material possess a surface area above 1000 m/g as determined through nitrogen adsorption isotherms and a pore size distribution of pores between 1-4 nm. The inorganic precursor is one or more metal oxide precursor, e.g. an oxide of silicon, aluminum, titanium, nickel, copper, cobalt, iron, ruthenium or rhodium. The metal oxide precursor is tetraethyl orthosilicate, aluminum isopropoxide and/or titanium butoxide. The metal oxide precursor comprises silica precursors such as tetraethyl orthosilicate and tetramethyl orthosilicate, where the ratio of silica precursor to template is 1:0.001-1:0.5. The mesoporous material comprises an inorganic oxide having an X-ray diffraction pattern: with mesoscale peaks of 1-6 degrees in 2 theta and at least one diffraction peak at angles above 15 degrees in 2 theta corresponding to the stacking distance of the template within the pores of the composition; and containing at least 1 wt.% of organic matter, which contains pterin groups. The mesoporous material comprises an inorganic oxide comprising functional groups at 1-30 wt.% on the internal porous surface that display local chirality, characterized by a circular dichroism spectra of its pre-extracted parent material with a positive peak displaying maximum at 300 nm arising from the chiral arrangement of tetrameric stacks within template.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The method comprises removing at least part of the template by solvent extraction to form a porous material. In the method, a co-structure directing agent capable of covalent or electrostatic interaction with the pore forming template is added in the forming step. The mesoporous material is capable of separating racemic mixtures of optical isomers, when the isomers are in the size range of the pore diameter derived from the method. Preferred Components: The ordered mesoporous materials comprise a chiral pore structure. The organic molecules of the template comprise: folic acid; or one or more folate derivatives, such as pterin, carboxypterin, 2,4-diamino-5-bromomethylpyrimidine, N-(4-((2-methyl-4-amino-5-pyrimidyl)methyl)amino-benzoyl)-L-glutamic acid, N-(4-((2,6-diamino-4-hydroxy-5-pyrimidyl)methyl)amino-benzoyl)-L-glutamic acid, 5-tert-butyl-dimethylsilyl- 2,3-di-O-isopropylidene, or derivatives of guanosine. The co-structured directing agent is composed of a basic group such as an amine moiety bonded to an alkyl spacer which may vary in length, and which bond to the inorganic precursor. The template comprises a fluorophore, which is a porphyrin type molecule and possesses fluorescent spectra with peak maximum at 450 nm and as Stokes-shift larger than 200 nm. The material has a final composition comprising folic acid (10-70%) within its pores. The template comprises a cosmetic product. The material has a final composition containing at least 10% of aminopropyl functional groups within its internal pore surface. EXAMPLE - No suitable example given.
