Substituted Tetraoxa[8]circulenes - New Members of the Liquid Crystal Family

A general method for the synthesis of substituted tetraoxa[8]circulenes based on alkylation of 2,3‐bis(bromomethyl)‐1,4‐dimethoxybenzene with acetylides is reported. Four of the compounds shows LC behavior, and the tetraoxa[8]circulenes are thus new candidates for discotic mesogens.
