摘要

Monte Carlo simulations are performed to study the phase diagram of liquid crystals formed by bent-core molecules with a strong transverse dipole moment deviating from their angular bisector.The results show that the strong dipolar interaction,after suppressing uniaxial phases,encourages biaxiality,which leads to a Landau point or even to a Landau line in the phase diagram,inducing a more stable biaxial nematic phase.It is also found that a deviation of dipole moment from the angular bisector also suppresses uniaxiality in the small bend-angle regime.
