Abstract

In this paper, we focused on polarity of smectic mesophase and biaxiality of nematic mesophase formed by V-shaped bent-core mesogens which have an acute-subtended angle (60°) instead of an obtuse-subtended angle (120°). Their switching properties of the former mesogens were investigated and compared with the latter mesogens. On the basis of the electro/optical data a plausible model for the smectic mesophase alignments was proposed. However, we have not confirmed yet the biaxiality of their nematic phases by our experimental data.
