Two homologous series of bent-shaped molecules composed of low bent-angle naphthalene central core and long alkoxy tail or alkylthio tail, N (1, 7)-n-OPIMB and N (1, 7)-n-SPIMB (n=20, 22), respectively, were synthesized. The mesomorphic properties were investigated by differential scanning calorimetry (DSC), polarizing optical microscopy (POM) and X-ray diffraction (XRD). Compared to the direct transition from the isotropic phase to the chiral B4 phase examined in N (1, 7)-n-OPIMB, N (1, 7)-n-SPIMB exhibited a rare Iso-N_col-Col_h-B4 phase sequence. The combination of the asymmetric low bent-angle 1, 7-naphathalene central core and the flexible long alkylthio tail is considered to play an important role in the formation of such a novel phase sequence.
