摘要：
Motivated by the recent discovery of a novel biaxial and orthogonal smectic polymeric liquid crystal with in-plane fluid order (smectic C(M)), we discuss defects allowed by its symmetry. Smectic C(M) has not yet been found in low molecular weight liquid crystals. We point out that the observation of defects provides a useful tool to distinguish smectic C(M) from other biaxial and fluid smectic phases known as smectics C and C2. The structure of a possible ferroelectric, but nonchiral phase (smectic C(P)) is briefly discussed.
