Abstract
A new homologous series of achiral banana-shaped mesogens ('Cn') has been s ynthesized and studied by classical techniques (optical microscopy, differe ntial scanning calorimetry, X-ray diffraction and electro-optic investigati ons). Complete miscibility with compounds of the n-OPIMB series shows that the short homologues (C5-C9) exhibit a frustrated B1 antiphase, while the l onger members (C10-C14) present a B2 smectic C phase. Electro-optic measure ments confirm this identification.
