WebNamely, a paranematic ordering favours parallel alignment of LC molecules, which breaks the isotropic symmetry imposed by the homeotropic anchoring condition. On the other hand, the coupling between cluster directors is relatively weak. Consequently, the orientational distribution function of cluster directors is expected to be isotropic if l N ...
