A number of 4-alkyl- and 4-alkoxy-4 prime -cyanobiphenyls and 4-alkyl-4 double prime -cyano-p-terphenyls with branched chains were prepared. Marked depressions in the liquid crystal transition temperatures were observed relative to those for the corresponding n-alkyl derivatives, although the melting points were affected to a smaller extent. The viscosities of 10 wt% solutions of the individual branched-chain materials in the commercial mixture E7 were determined at 0 degree C and 20 degree C and substantial increases in the measured bulk viscosities were recorded.
