Abstract
Described herein are copolymers constructed from chiral, non-racemic monomers, which self-assemble to photonic crystals. The difficulty of incorporating chiral elements into photonic crystals has limited the ability to generate unique bandstructures for different circular polarizations of light. The materials and methods described herein relate to easily, predictably fabricating chiral photonic crystals having desirable optical properties.
