The synthesis of alkoxybromotriphenylenes: new discotic liquid crystals and valuable precursors to ‘mixed tail’ discotics

Abstract
The phenolic moieties of hydroxyalkoxytriphenylenes are derivatized and reduced to yield alkoxytriphenylenes possessing reactive sites for aromatic substitution; simple bromination affords the first triphenylene discotic liquid crystal having only three alkoxy tails.
