一个新的同源系列的非手性香蕉形介晶（'Cn'）已被合成和研究的经典技术（光学显微镜，差示扫描量热法，X射线衍射和电光调查）。与n-OPIMB系列化合物的完全相容性表明，短同系物（C5-C9）表现出受抑的B1反相，而较长的成员（C10-C14）呈现B2近晶C相。电光测量证实了这一点。
A new homologous series of achiral banana-shaped mesogens ('Cn') has been synthesized and studied by classical techniques (optical microscopy, differential scanning calorimetry, X-ray diffraction and electro-optic investigations). Complete miscibility with compounds of the n-OPIMB series shows that the short homologues (C5-C9) exhibit a frustrated B1 antiphase, while the longer members (C10-C14) present a B2 smectic C phase. Electro-optic measurements confirm this identification.
