Methods of preparing organosilica materials, which is a polymer comprising independent siloxane units of Formula [Z 3 Z 4 SiCH 2 ] 3 (I), wherein each Z 3 represents a hydroxyl group, a C 1 -C 4 alkoxy group or an oxygen atom bonded to a silicon atom of another siloxane unit and each Z 4 represents a hydroxyl group, a C 1 -C 4 alkoxy group, a C 1 -C 4 alkyl group, or an oxygen atom bonded to a silicon atom of another siloxane, in the absence of a structure directing agent and/or porogen are provided herein. Processes of using the organosilica materials, e.g., for gas separation, etc., are also provided herein. |
