Abstract: Provided herein chiral derivatization reagents for use in separating and detecting of amine containing enantiomers. The said chiral derivatization reagents provide a combination of improved detectable properties to facilitate various downstream analyses. In particular, the chiral derivatization reagents include at least one chiral carbon atom; at least one strongly basic moiety; at least one chromophore moiety or at least one fluorophore moiety; and at least one reactive group. The present disclosure further provides methods for analyzing amine-containing enantiomeric isomers using a chromatographic separation device and a mass spectroscopy.

Abstract: 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.
