Induction of smectic layering in nematic liquid crystals using immiscible components. 5. Laterally attached side-chain liquid crystalline poly(norbornene)s and their low molar mass model compounds with short fluorocarbon segments

5-[[[2′,5′-Bis[(4″-n-((perfluoroalkyl)alkoxy)benzoyl)oxy] benzyl]oxy]carbonyl]bicyclo[2.2.1]hept-2-enes with short fluorocarbon segments were polymerized by ring-opening metathesis polymerization in THF at room temperature using Mo(CHCMe2Ph)(N-2,6-iPr2Ph)(OtBu) 2 as the initiator. Although hydrocarbon and fluorocarbon segments as short as three methylenic units each induce smectic layering in the corresponding 2,5-bis{[4′-(n-(perfluoroalkyl)alkoxy)benzoyl]oxy}toluene model compounds, the polymers require at least eight and three, or five and four methylenic units in the hydcrocarbon and fluorocarbon segments, respectively, to organize into smectic layers; polymers with shorter hydrocarbon and/or fluorocarbon segments are nematic.
