Bent-shaped liquid crystals based on 4-substituted 3-hydroxybenzoic acid central core
We present the synthesis and mesomorphic properties of bent-shaped liquid crystals with 3-hydroxybenzoic acid central core. The mesomorphic properties were tuned by lateral substitution in the position 4 of the central unit and by t...
