  A glassy cholesteric liquid crystalline composition comprising compounds with a volume-expanding core bound to one or more hybrid chiral-nematic (or Ch) pendant moieties and a method of producing oriented films of such compounds. The Ch pendant moieties are comprised of chiral spacer groups connected to the core via linker groups and nematic groups linked to the chiral spacer groups. Thin-films of the composition are morphologically stable for extended periods of time. Also, the thin-films are able to selectively interact with light from the visible to near-IR wavelength range.
