1. An organosilica material, which is a polymer of at least one independent monomer unit of Formula [Z1OZ2OSiCH2]3 (I), wherein Z1 and Z2 each independently represent a hydrogen atom or a bond to a silicon atom of another monomer unit and at least one other monomer unit selected from the group consisting of:

  • (i) an independent unit of Formula Z3OZ4Z5Z6Si (II), wherein each Z3 represents a hydrogen atom or a bond to a silicon atom of another monomer unit; and

    Z4, Z5 and Z6 are each independently selected from the group consisting of a hydroxyl group, a C1-C4 alkyl group, a nitrogen-containing C1-C10 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 unit;

    (ii) an independent unit of Formula Z7Z8Z9Si—

    R1

    SiZ7Z8Z9 (III), wherein each Z7 independently represents a hydroxyl group or an oxygen bonded to a silicon atom of another monomer unit;

    each Z8 and Z9 independently represent a hydroxyl group, a C1-C4 alkyl group or an oxygen bonded to a silicon atom of another monomer unit; and

    each R1 represents a nitrogen-containing C2-C10 alkylene group; and

    (iii) a combination thereof.
