Anchored in hexagons: The molecules shown display two new complex liquid-crystalline phases formed by arrays of hexagonal cylinders, each hexagon comprising either three or six molecules. The phase type can be selected by choosing the right size ratio between the π-conjugated aromatic core (the anchor) and the flexible chain. One of the phases is the first columnar liquid crystal with trigonal symmetry.
