Abstract
Communication: Liquid crystals with one or more trans-1,3-dioxane buil ding blocks (see Figure) combine high dielectric anisotropy with low b irefringence and favorable mesogenic and viscoelastic properties. A ne w building-block-oriented synthetic strategy is described that offers convenient access to trans-1,3-dioxane-based core structures with vari ous alkyl or alkenyl side chains or with a difluorovinyloxy(methyl) gr oup as a polar end group.
