A good connection : A polyphilic oligothiophene derivative (see formula) forms a complex liquid‐crystalline phase, in which the π‐conjugated rods are organized in a honeycomb‐like network of square cylinders (see picture). This arrangement opens new possibilities for the directed organization of π‐conjugated organic materials into complex superstructures and patterns for the design of functional devices by means of liquid‐crystal self‐assembly.
