Porous inorganic/organic hybrid materials with ordered domains for chromatographic separations and processes for their preparation

Porous particles comprising ordered domains ordered radially, the particles having ordered pores that are arranged such that they extend substantially parallel to radii of the particles, and wherein said particles have a specific surface area of about 50 to 800 m2/g, an average pore diameter of about 50 to 500 Å, or a specific pore volume of about 0.25 to 1.5 cm3/g.
