Abstract

Smectic B2 phase of bent-core 1,3-phenylene bis{4-[(4-dodecyloxybenzoyl)sulfanyl]benzoate} (12OSOR) and a mixture 12R9AF have been studied using dielectric and electrooptic methods. 12R9AF is a mixture of bent-core 12OSOR and calamitic chiral MHPSBO9 materials. The B2 phase of 12R9AF mixture is shifted to lower temperatures by about 10 °C in comparison with pure 12OSOR. Spontaneous polarization of the mixture is comparable with spontaneous polarization of pure compound. Dielectric measurements were done using dielectric spectrometer based on Agilent 4294A impedance analyzer. Dielectric spectra measured with bias field for B2 phase of 12OSOR and 12R9AF show two well separated relaxation processes.
