Synthesis and Liquid Crystal Behaviour of Further 4,4"-Disubstituted 2'-Fluoro-1,1':4',1"-Terphenyls

Further to earlier work on the liquid crystal properties of fluoro-1,1':4',1"-terphenyls we have now extended this series to include terminally fluoro- and cyano-substituted 2'-fluoro-1,1':4',1"-terphenyls, chiral 2'-fluoro-1,1':4',1"-terphenyls, and esters derived from 2'-fluoro-1,1':4',1"-terphenyls and incorporating the alkylcyclobutyl group.The preparations and transition temperatures for these series of compounds are presented and their transition temperatures and mesophase types are discussed.An interesting result from this work was the appearence of an S*C phase for one chiral homologue and of SC phases for the esters incorporating the alkylcyclobutyl group.The SC formation is attributed to the presence of the fluoro-substituent.Keywords: terphenyls, fluoroterphenyls, smectic C phases, cyclobutyl esters.

Synthesis and Evaluation of Some 4,4''-Disubstituted Lateral Fluoro-1,1':4',1''-terphenyls

A number of laterally fluorinated 4,4''-di-n-alkyl-, 4,4''-di-n-alkoxy- and 4-n-alkyl-4''-n-alkoxy-1,1':4',1''-terphenyls of structure (I) have been synthesised, with the lateral fluoro-substituent in the central benzene ring. The nematic and smectic thermal stabilities for all three series of compounds, have been examined.A typical example is (I), X = n-C5H11, Y = n-C3H7, C-N 50 deg C and N-I 140.6 deg C.For the 4,4''-di-n-alkyl-1,1':4',1''-terphenyls, the position of the lateral fluoro-substituent with respect to the longest n-alkyl chain is found to be important in determining the smectic behaviour of this class of compound.By using a combination of optical microscopy, X-ray diffraction and miscibility studies, the complex smectic behaviour of the higher homologues of this series has also been investigated.A comparison of the liquid crystal behaviour of the laterally fluorinated terphenyls of structure (I) with their non-fluorinated analogues is also given.A selected number of these compounds, have been further examined to assess their usefulness as high TN-I additives for multiplexed mixtures used in electro-optic display devices.
