Liquid Crystals from <i>C</i>₃‐Symmetric Mesogens for Second‐Order Nonlinear Optics

Octopolar tris[(phenyl)ethynyl]benzenes with high second-order nonlinear optical (NLO) activity form discotic liquid-crystalline mesophases whose properties depend on the length of the alkoxy chains. The molecules self-organize in a non-centrosymmetric fashion in the bulk phase which enables the construction of a simple, efficient, NLO device (see picture).
