A series of C 2-symmetric compounds with different core sizes and varying lengths and numbers of alkoxy side chains were prepared, and the factors influencing their liquid crystalline mesophase behaviour were investigated. The compounds studied were based on benzophenone, dibenzylidene-acetone, and 1, 9-diphenyl-nona-1, 3, 6, 8-tetraen-5-one cores with either 1 or 2 linear alkoxy side chains. The side chains were varied in length ...
