Bent- and straight-rod shaped liquid crystalline amides 1-3 were designed and synthesized, and their thermodynamic behaviors were investigated by polarized optical microscopy and differential scanning calorimetry, and their layer distances were measured by X-ray diffraction. Weak or strong hydrogen bonds were observed in variable-temperature FT-IR spectra for bent-rod shaped compounds 1 possessing a long alkoxy chain (OR2), straight-rod shaped compounds 2, and straight-rod shaped 3 in their smectic C, smectic C x, and smectic A phases, respectively. Thus, these liquid crystalline amides could generate linear molecular aggregates in their smectic layers by the lateral intermolecular hydrogen bonds.
