  摘要：

  A new series of achiral banana-shaped compounds ("S-n'') has been synthesised and studied by the classical techniques (optical microscopy, differential scanning calorimetry, X-ray diffraction and electro-optic investigations). The short homologues (S-6,S-7) present an intercalated smectic B6 and a two-dimensional B1 phase. The intermediate S-8-S-10 compounds only form a B1 phase while the mesophase of long homologues (S-11-S-16) is identified as a switchable smectic B2 mesophase.

  A homologous series of 1,2,4,5-tetra-(4-alkoxybenzoyloxy)benzenes (2, R = C4H9, C6H13 to C16H33 and C18H37) has been synthesised. Optical microscopy revealed that the compounds with R = C4H9, C6H13 to C10H21 have a nematic phase, compounds with R = C11H23 to C14H29 have nematic and smectic C phases and compounds with R = C15H31, C16H33 and C18H37 have only a smectic C phase. The T-N-I values show an 'odd-even' alternation which is typical of calamitic systems. The refractive indices for aligned samples of compound 2h (R = C10H21) demonstrate that the nematic phase is uniaxial.

  We have synthesized a new class of liquid crystalline (LC) organic radical compounds 2, which are the C-2-symmetric derivatives of the previously reported compounds 1 containing a chiral nitroxide unit and an ester group in the mesogen core, and their LC properties have been fully characterized. The enantiomerically enriched 2 showed N* and SmC* phases. Their LC phase transition behavior is similar to that of 1, whereas the ferroelectric properties of the SmC* phase of (2S,5S)-2 differed from those of (2S,5S)-1. We discuss the origin of this difference in terms of their molecular structures optimized by molecular orbital calculations.
