Abstract:
1. A method of preparing a porous hybrid inorganic/organic particle or monolith comprising ordered domains and having a chromatographically-enhancing pore geometry, comprising the steps of: (a) forming a pore restructuring template; (a′) obtaining a porous hybrid inorganic/organic particle or monolith having a choromatographically-enchancing pore geometry; (b) restructuring the pores of the porous hybrid inorganic/organic particle or monolith by contacting the pores of the inorganic/organic particle or monolith with the pore restructuring template, to thereby restructure the pores into ordered domains; and (c) removing the pore restructuring template from the restructured pores; to thereby prepare the porous hybrid inorganic/organic particle or monolith comprising ordered domains and having a chromatographically-enhancing pore geometry, wherein the pores of a diameter of 34Å or less contribute less than about 110 m wherein the particle or monolith has a specific pore volume of about 0.25 to 1.5 cm and wherein diffraction peaks are present for said ordered domains in the range of 0.8 to 20° 2θ, and wherein the diffraction peak maxima observed for said particle or monolith exhibit a 20 position that excludes diffraction peaks ranging from about 20° to about 23° 2θ resulting from atomic-range order that are associated with amorphous material.
