Nematic compounds with a negative DC antisotropy, characterized by the formula I STR1 in which m=1 or 2, r is zero or 1 and m+r=1 or 2, and R1 and R2 are identical or different and are selected from alkyl and alkoxy groups each havin
The Synthesis and Liquid-Crystal Transition Temperatures of Some Fluoro-Substituted Benzonitriles
Kelly, Stephen M.,Schad, Hanspeter

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.

The synthesis and some important properties of the 1-(trans-4 prime -n-alkylcyclohexyl)-2-(4 double prime -cyanophenyl)ethanes - where n-alkyl equals C//1 to C//7 - are described.
