Abstract: Chiral polymer microspheres have a porous structure of a concentric multi-shell structure. Each layer of the multi-shell structure is optically and structurally anisotropic. The optical axes of adjacent layers have a sequential slight twist. All layers of the multi-shell structure generate a helix configuration and the chiral polymer microspheres are optically active. A method for preparing the chiral polymer microspheres, includes: forming a homogeneous liquid crystal mixture; dispersing the liquid crystal mixture into a continuous phase to form liquid crystal droplets through an emulsification process; polymerizing the reactive liquid crystal to form intermediate microspheres; and removing the one non-reactive liquid crystal and the chiral additive to form the chiral polymer microspheres. The chiral polymer microspheres have a porous structure and a swelling ability, and can be used as the stationary phase in chiral chromatograph, improving separation efficiency.

Abstract: Methods are provided for fabricating functional nanostructures (e.g., nanowires/nanofibers) via chemical vapor deposition polymerization of paracyclophanes or substituted paracyclophanes onto and through a structured fluid, such as a film of liquid crystals, on a substrate. A one-step process is provided that does not require the use of any solid templates, nor does it require any volatile solvents, additives or catalysts. The resulting nanowires/nanofibers can be in the form of aligned nanowires/nanofibers arrays supported on any solid material, in the form of nanofibers mats supported on porous materials, or as individual free-standing nanowires/nanofibers. By using chiral liquid crystals, chiral nanofibers can be fabricated. The functional nanowires/nanofibers can contain one or more type of surface reactive groups that allows for post surface chemical modifications on the nanowires/nanofibers. Such nanostructures can be used in a range of different applications, including in biomedical applications.
