Dynamics of the Nematic Phase Formed by Achiral Banana-shaped Materials

We synthesized a series of achiral non-symmetric banana-shaped compounds. Some of them were found to exhibit a nematic phase. We are strongly interested in this nematic phase composed of the bent molecule. On the basis of the assumption that the dynamics of the nematic phase of the banana-shaped molecules could be much different from the conventional thermotropic nematic phase of the rod-like molecules, we carried out the dynamic light scattering measurement. And we will present the unique phase behaviour of newly synthesised non-symmetric banana-shaped material with dichloro-substituted mesogen.
