摘要

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 ...
