Patent ID: 8658277

Claim:
A porous hybrid inorganic/organic particle or monolith comprising ordered domains and having a chromatographically-enhancing pore geometry, prepared by a method comprising the steps of: (a) forming a pore restructuring template; (b) restructuring the pores of the porous hybrid inorganic/organic particle or monolith by contacting the pores of the porous hybrid 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; wherein the pores of a diameter of 34 Å or less contribute less than about 110 m 2 /g to the specific surface area of the particle or monolith and the ratio of the micropore surface area to the specific surface area is from 0.036 to 0.273, wherein the particle or monolith has a specific pore volume of about 0.25 to 1.5 cm 3 /g and an average pore diameter of about 50 to 500 Å, 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 2θ position that excludes diffraction peaks ranging from about 20° to about 23° 2θ resulting from atomic-range order that are associated with amorphous material.
