Abstract

The new bis-4-(hexyloxy)benzamide and bis-4-(dodecyloxy)benzamide derivatives of macrocyclic ligands [18]aneN2O4 (L1 and L2) and [18]aneN2S4 (L3 and L4) have been prepared and characterized by1H and13C NMR spectroscopy, differential scanning calorimetry and optical microscopy. The nonmesogenic ligands L3 and L4 react with [Pd(CH3CN)4][BF4]2 to give the cationic complexes [Pd(L3)][BF4]2 and [Pd(L4)][BF4]2. [Pd(L4)][BF4]2 shows mesomorphic behaviour affording a smectic mesophase.
