The 1,4-disubstituted bicyclo[2.2.2]octane ring has been incorporated in certain cyano-substituted systems to produce series of mesogens exhibiting wide-range nematicphases. 1-(4-Cyanophenyl)- and 1-(4′-cyanobiphenyl-4-yl)-4-n-alkylbicyclo[2.2.2]octanes are colourless stable materials, whose nematicphases are of low birefringence and of positive dielectric anisotropy. This combination of properties
