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.
