Dielectric response of the B2 phase

A compound consisting of banana-shaped molecules was synthesized and well purified. The sample shows the B2 phase which was characterized by dielectric spectroscopy. Two relaxation ranges were detected. The high frequency one, related to the reorientation about the long molecular axis, was observed in the isotropic phase, too. The increments point to a strong positive dipole correlation in the B2 state. There are arguments that low frequency mechanism can not be connected with the reorientation about the short molecular axis. AFM-investigations give no hints to a super- structure. Therefore, this absorption was related to a collective response of ferroelectric clusters.
