We report the observation of a biaxial nematic phase in a bent-core molecular system using polarizing microscopy, electro-optics, and dielectric spectroscopy, where we ﬁnd that the biaxiality exists on a microscopic scale. An application of electric ﬁeld induces a macroscopic biaxiality and in consequence gives rise to electro-optic switching. This electro-optic effect shows signiﬁcant potential in applications for displays due to its fast high-contrast response. The observed electro-optic switching is explained in terms of the interaction of the ferroelectric clusters with the electric ﬁeld. © 2010 American Institute of Physics.
