Alignment and Alignment Transition of Bent Core Nematics

We report on the alignment of nematics consisting of bimesogen bent core molecules of chlorine substituent of benzene derivative and their binary mixture with rod like nematics. It was found that the alignment layer made from polyimide material, which is usually used for promoting vertical (homeot...

Alignment and Alignment Transition of Bent Core Nematics
