Substituted tetraoxa[8]circulenes - New members of the liquid crystal family

Eskildsen, J?rgen,Reenberg, Theis,Christensen, J?rn Bolstad

, p. 1637 - 1640 (2007/10/03)

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.
