Abstract
A structure and apparatus is described which utilizes the intrinsic self-assembling or aligning process of liquid crystal (LC) molecules to form an ordered structure, such as a structure having nematic or cholesteric ordering. The invention includes subtracting a constituent from a structure that includes a liquid crystal, to form a `mold` or polymer matrix on a molecular level. By adding and/or subtracting materials to or from the mold, a liquid crystal-like structure may be obtained. This structure includes all or at least some non-LC material, while exhibiting some LC characteristic. The liquid crystal-like structure overcomes the drawbacks of LCs such as temperature sensitivity and mechanical instability.
