Abstract:
1. A porous inorganic/organic hybrid monolith material, comprising a chromatographically-enhancing pore geometry and having the formula SiO 2 /(R 2 p R 4 q SiO t ) n or SiO 2 /[R 6 (R 2 r SiO t ) m ] n wherein R 2 and R 4 are independently C 1 -C 18 aliphatic, styryl, vinyl, propanol, or aromatic moieties, R 6 is a substituted or unsubstituted C 1 -C 18 alkylene, alkenylene, alkynylene or arylene moiety bridging two or more silicon atom, p and q are 0, 1 or 2, provided that p+q=1 or 2, and that when p+q=1, t=1.5, and when p+q=2, t=1; r is 0 or 1, provided that when r=0, t=1.5, and when r=1, t=1; m is an integer greater than or equal to 2, and n is a number from 0.03 to 1.
