Unusual physical properties in B phase of polar bent-core thioester compound
bent-core thioester
ferroelectric phase
spontaneous polarization
electro-optic effects
dielectric relaxation
molecular and collective processes
Bent-core compound, 4-chloro-1,3-phenylene bis4-[(n-undecyloxybenzoyl)-sulfanyl]benzoate, has been studied by dielectric spectroscopy, DSC calorimetry, and electro-optic methods. As found, the spontaneous polarization of the B phase is by one order of magnitude smaller than for B 2 phases of nOSOR series studied by us before. Its temperature dependence is characteristic for B 1 phase, observed for shorter homologues of nOSORs. Measurements of the complex electric permittivity were carried out in the frequency range from 40 to 15 MHz using gold-coated electrodes. Electro-optic studies have been done applying AWAT HG 1.9 µm cells with strongly rubbed polymer layers. Such cells facilitate inhomogeneous planar alignment, which under strong electric field transforms into a mono-domain exhibiting switching behavior. Dielectric and electro-optic data of bent-core compounds will be discussed taking into account molecular structure and phase structure as well.
