Tricycloquinazoline (CAS NO.195-84-6) has been found to function as the core fragment for a remarkable new family of discotic mesogens, which have C3 symmetry and six aliphatic side chains. Eight representative homologous 2,3,7,8,12,13-hexa(thioalkoxy)tricycloquinazoline derivatives were synthesized, with alkyl side chain lengths varying from three to eighteen carbon atoms.
