In this study a new series of bent-core liquid crystals based on laterally substituted 7-hydroxynaphthalene-2-carboxylic acid is presented. All compounds exhibit broken-layer type columnar phases. For CH3 laterally substituted compounds with a longer chain we found a smectic A above a columnar phase on cooling from the isotropic phase. Additionally, for CH3-substituted compounds with the longest chains two switchable columnar phases (B1RevT) occurred below the SmA phase.
