A simple method for synthesizing alkoxy‐cyanotolanes (nOCDP) is presented. Optical and electro‐optical properties of three nOCDP liquid crystals and an eutectic mixture were evaluated in their nematic range. Birefringence and viscoelastic coefficient results of nOCDP are compared with alkyl‐cyanotolanes at reduced temperatures. Molecular conformation is found to make an important contribution to the observed birefringence, and so does clearing temperature to the measured viscoelastic coefficient.
