contrast to their hydrocarbon analogues which exhibit only nematic mesophases, poly5-[[[2‘,5‘-bis[(4‘‘-(n-(dimethylsiloxyl)alkoxy)benzoyl)oxy]benzyl]oxy]carbonyl]bicyclo[2.2.1]hept-2-ene}s and their low-molar-mass model compounds exhibit smectic C mesophases. Since nematic liquidcrystals can be forced into layers by terminating their hydrocarbon substituents not only with fluorocarbon segments but also
