T-shaped molecules are designed in such a way that they self-organize
into nanoscale liquid crystalline honeycombs based on polygons
with any chosen number of sides. One of the phases reported
here is a periodic organization of identical pentagonal cylinders;
the other one is a structure composed of square-shaped and triangular
cylinders in the ratio 2:1. These two different packing motifs
represent duals of the same topological class. The generalization
of the concept applied here allows the prediction of a whole
range of unusual complex liquid crystalline phases.
