Abstract
Disclosed is a method for preparing a solid-state helical photonic crystal structure. The method includes: mixing a nonreactive chiral dopant with a reactive nematic mesogen, followed by curing to form a helical cholesteric liquid crystal; and removing the chiral dopant from the cholesteric liquid crystal while maintaining the helical structure of the cholesteric liquid crystal, to form a solid-state helical liquid crystal.
