Abstract
Mesogenic compounds having a structure of Formula (I), (II) or (III): where A, B, X1, L, TG, m, and n are defined as in claim 1. Compositions containing these compounds, articles made from these polymerized and prepolymerized compositions, and methods of estimating the elastic constants and anchoring constants of a liquid crystal materials and mapping topological defect structures in liquid crystals using these compounds.
