Jp. Bedel et al., Physical characterization of B1 and B2 phases in a newly synthesized series of banana shaped molecules, LIQ CRYST, 27(1), 2000, pp. 103-113
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.
