The invention provides cross-linked lyotropic liquid crystal (LLC) copolymers having ordered nanometer-sized pores lined with functional groups. The copolymers are formed by copolymerizing LLC monomers with strong LLC character and functionalized monomers with no or weak LLC character to form an LLC phase. Both the LLC monomers and the functionalized monomers contain hydrogen-bonding groups and hydrogen-bonding is believed to assist in the formation of the LLC phase of the blended mixture. Different classes of functional groups useful for the invention include, but are not limited to, acidic groups, basic groups, catalytic groups, oxidizing agents, reducing agents, polymerization initiators, binding agents, optically active groups, and electrically active groups. The invention also provides methods for making the cross-linked LLC copolymers of the invention. In these methods, the LLC monomer and the functionalized monomer are blended in a polar solvent, thereby allowing self-assembly of the first and second monomer into an LLC phase. The LLC phase in then cross-linked with retention of the LLC microstructure.
A cross-linked co-polymerized lyotropic liquid crystal (LLC) polymer comprising ordered nanopores, the walls of the nanopores comprising a multiplicity of functional groups, wherein the LLC polymer is a co-polymer of a first monomer which is a LLC monomer having strong LLC character, the first monomer comprising a first headgroup, a first polymerizable platform, and a first hydrogen-bonding linkage between the first headgroup and the first polymerizable platform, and a second monomer comprising a second headgroup comprising a functional group, a second polymerizable platform, and a second hydrogen-bonding linkage between the second headgroup and the second polymerizable platform.
A method of preparing a cross-linked functionalized lyotropic liquid crystal (LLC) polymer comprising:
