摘要：
A new series of the shish-kebab-type chiral polymers were synthesized by polycondensation of 2,5-bis(4-alkoxylbenzoyloxy)hydroquinone and diacyl dichloride. By means of differential scanning calorimetry, polarizing optical microscopy, wide-angle X-ray scattering, and polarimetric analysis, we found that all the chiral polymers were optically active and formed a smectic C phase when being heated to above their melting temperatures.
