Abstract

Organosilica materials, which are a polymer of at least one independent monomer of Formula [Z1OZ2OSiCH2]3 (I), wherein Z1 and Z2 each independently represent a hydrogen atom, a C1-C4 alkyl group or a bond to a silicon atom of another monomer and at least one other monomer is provided herein. Methods of preparing and processes of using the organosilica materials, e.g., for gas separation, color removal etc., are also provided herein.
