Abstract

Organosilica materials, which are a polymer of at least one independent monomer of Formula [Z 1 OZ 2 OSiCH 2 ] 3 (I), wherein each Z 1 and Z 2 independently represent a hydrogen atom, a C 1 -C 4 alkyl group or a bond to a silicon atom of another monomer and at least one other trivalent metal oxide monomer are provided herein. Methods of preparing and processes of using the organosilica materials, e.g., for catalysis etc., are also provided herein.

First claim

What is claimed is:

1 . An organosilica material, which is a polymer of at least one independent monomer of Formula [Z 1 OZ 2 OSiCH 2 ] 3 (I), wherein each Z 1 and Z 2 independently represent a hydrogen atom, a C 1 -C 4 alkyl group or a bond to a silicon atom of another monomer and at least one other trivalent metal oxide monomer.

2 . The organosilica material of claim 1 , wherein each Z 1 and Z 2 independently represent a hydrogen atom, a C 1 -C 2 alkyl group or a bond to a silicon atom of another monomer.

3 . The organosilica material of claim 1 , wherein each Z 1 and Z 2 independently represent a hydrogen atom, ethyl or a bond to a silicon atom of another monomer.

4 . The mesoporous organosilica material of claim 1 , wherein the at least one other trivalent metal oxide monomer is
(i) an independent unit of formula M 1 (OZ 3 ) 3 (II), wherein M 1 represents a Group 13 metal and each Z 3 independently represents a hydrogen atom, a C 1 -C 6 alkyl or a bond to a silicon atom of another monomer; or (ii) an independent unit of formula (Z 4 O) 2 M 2 -O—Si(OZ 5 ) 3 (III), wherein M 2 represents a Group 13 metal and each Z 4 and each Z 5 independently represent a hydrogen atom, a C 1 -C 6 alkyl group or a bond to a silicon atom of another monomer.

5 . The organosilica material of claim 4 , wherein at least one unit of formula (II) is present, wherein M 1 is Al or B and each Z 3 independently represents a hydrogen atom, a C 1 -C 4 alkyl group or a bond to a silicon atom or another monomer.

6 . The organosilica material of claim 4 , wherein at least one unit of formula (III) is present, wherein M 2 is Al or B; and each Z 4 and each Z 5 independently represent a hydrogen atom, a C 1 -C 4 alkyl group or a bond to a silicon atom of another monomer.

7 . The organosilica material of claim 1 further comprising a monomer selected from the group consisting of:
(i) an independent unit of formula [Z 6 OZ 7 SiCH 2 ] 3 (IV), wherein each Z 6 represents a hydrogen atom, a C 1 -C 4 alkyl group or a bond to a silicon atom of another monomer and each Z 7 represents a hydroxyl group, a C 1 -C 6 alkyl group or an oxygen atom bonded to a silicon atom of another monomer;
(ii) an independent unit of formula Z 8 OZ 9 Z 10 Z 11 Si (V), wherein each Z 8 represents a hydrogen atom or a C 1 -C 4 alkyl group or a bond to a silicon atom of another monomer; and Z 9 , Z 10 and Z 11 are each independently selected from the group consisting of a hydroxyl group, a C 1 -C 4 alkyl group, a C 1 -C 4 alkoxy group, a nitrogen-containing C 1 -C 10 alkyl group, a nitrogen-containing heteroaralkyl group, a nitrogen-containing optionally substituted heterocycloalkyl group, and an oxygen atom bonded to a silicon atom of another monomer; and
(iii) an independent unit of formula Z 12 Z 13 Z 14 Si—R—SiZ 12 Z 13 Z 14 (VI), wherein each Z 12 independently represents a hydroxyl group, a C 1 -C 4 alkoxy group or an oxygen atom bonded to a silicon atom of another comonomer; each Z 13 and Z 14 independently represent a hydroxyl group, a C 1 -C 4 alkoxy group, a C 1 -C 4 alkyl group or an oxygen bonded to a silicon atom of another monomer; and R is selected from the group consisting of a C 1 -C 8 alkylene group, a C 2 -C 8 alkenylene group, a C 2 -C 8 alkynylene group, a nitrogen-containing C 2 -C 10 alkylene group, an optionally substituted C 6 -C 20 aralkyl and an optionally substituted C 4 -C 20 heterocycloalkyl group; and
(iv) a combination thereof.

8 . The organosilica material of claim 1 , wherein the organosilica has an average pore diameter between about 1.5 nm and about 20.0 nm.

9 . The organosilica material of claim 1 , wherein the organosilica material has a total surface area of about 200 m 2 /g to about 2500 m 2 /g.

10 . The organosilica material of claim 1 , wherein the organosilica material has a pore volume about 0.1 cm 3 /g to about 5.0 cm 3 /g.
