We introduced new poly(2-vinylcyclopropane)s carrying two perfluoroalkyl mesogens per repeat unit at the same main chain carbon atom. The relative lengths of the hydrocarbon-fluorocarbon segments were varied. Copolymers with a non-mesogenic 2-vinylcyclopropane were also prepared. X-ray diffraction studies proved the formation of smectic mesophases, the type of which depended on. the chemical nature of the polymers: SmB2, SmI2 (or SmF2), and SmA(d) We emphasize the role of intramolecular microphase segregation in determining the mesophase behavior and structure.
