The Synthesis and Liquid Crystal Behavior of p-Benzotrifluoride Compounds II

Four compounds with the general structure R-X-Y-CH2-CH2-Ph-CF3 were synthesized, where X is a 1,4-disubstituted trans-cyclohexyl ring, Y is a phenyl ring, and R is a n-alkyl group.The synthetic procedure is discussed and the structural assignments were confirmed by NMR spectroscopy.The liquid crystal behavior of these compounds was evaluated by DSC and polarizing microscopy.They might be used in fast switching liquid crystal mixtures.

The Synthesis and Liquid-Crystal Transition Temperatures of Some Fluoro-Substituted Benzonitriles

Various laterally fluoro-substituted benzonitriles have been prepared containing a trans-4-(n-alkyl)cyclohexane ring linked to the 4-position of the benzonitriles either through a methyleneoxy (-CH2O-) or an ethylene (-CH2CH2-) bridge.The bridging group links the benzonitrile and cyclohexane rings either directly or through an additional 1,4-bonded cyclohexane or benzene ring.The synthesis and liquid-crystal transition temperatures of these new compounds are described.In several cases the nematic-isotropic transition temperatures of F-substituted benzonitriles are found to be higher than those of the non-laterally substituted analogues.
