ABSTRACT:

In recent years new approaches to the synthesis of mesoporous materials have been developed focusing on the use of non-surfactant templates that can offer new functions within the mesoporous produced without the need to eliminate the pore forming agent. Such functions may include the use of pharmaceutically active compounds as pore forming agents or the use of chiral compounds to transcribe a chiral surface within the pores. Furthermore, avoiding the need to remove the pore template by calcination has both environmental and economic consequences.

Recently we reported the synthesis of mesoporous material NGM-1 nanoporous guanosine material-1) which is prepared through the use of supramolecular template guanosine monophosphate (GMP), a nucleotide monomer in messenger RNA. The supramolecular assembly of GMP occurs via the formation of G4-quartets, hydrogen bonded species that supported via pi-stacking interactions form chiral hexagonal columnar species. These are stabilized via the  formation of cations (cations (Na+, K+, Rb+, Sr2+) which may direct the formation of various supramolecular structures.

The synthesis and structural properties of a variety of GMP template materials will be reported, highlighting the effects that the pore template has on the pore surface. Evidence based on a variety of techniques including X-ray diffraction, transmission electron microscopy and circular dichroism as well as other spectroscopic methods will be utilized in order to show the chiral transcription of the template within the pores of the ordered mesoporous materials produced.
