Disc like molecule which was formed by fused polyaromatics was found to be with discotic liquid crystal properties. So it has been researched thoroughly. We take 5,6,11,12,17,18-hexaazatrinaphthylene (HTN) as our central core and synthesize Hexa-O-substituted hexaazatriphenylene, a new molecule with discotic liquid crystal properties successfully.

Unsymmetrical discotic liquid crystals based on hexaazatriphenylene(HAT) have not been published until today.We have used tetrahydoxyquinone as the starting material to synthesis unsymmetrical discotic liquid crystals based on HAT and investigate their properties of liquid crystal.
