    Abstract: A microphase stabilized ferroelectric liquid crystal (MSFLC) and optical device prepared therefrom are provided. The MSFLC includes a block copolymer, comprising at least one non-liquid crystal polymer block and at least one liquid crystalline polymer block including a chiral mesogenic side group, the block copolymer comprising domains of the non-liquid crystalline block of the non-liquid crystalline polymer and domains of chiral mesogenic polymer such that the domains form an inverted cylinder morphology. The volume percent and block size of the chiral mesogenic group are selected such that the spacings between cylinders is sufficient to permit switching of the chiral mesogenic group between two stable orientations.
