In the conventional liquid crystals, the mesogenic units usually have the shape of rod-like(calamitic) or disc-like(discot- ic). The X-shaped or T-shaped mesogens were also reported in polymeric liquid crystals.1,2 In supramolecular liquid crystals self-assembled by non-convalent interactions, there have been many examples in calamitic liquid crystals from hydrogen- bonding extended mesogens,3 and discotic hydrogen-bonding associated mesogens from ...
