Anchor shaped molecules self‐organize into two new complex liquid‐crystalline phases formed by arrays of hexagonal cylinders, each hexagon comprising three or six molecules, as described by C. Tschierske and co‐workers in the Communication on page 6080 ff. The phase type can be selected by changing the ratio of the π‐conjugated aromatic core (the anchor) and the flexible chain. One of the phases is the first columnar liquid crystal with trigonal symmetry, which is of interest for nonlinear optical applications.
