The extremely persistent self-assembly of ovalene tetraesters (see picture) into liquid-crystalline columns from below room temperature to over 375°C gives these first soluble derivatives of "circumnaphthalene", one of the most stable mesophases known. The close contact of the large π systems within the columnar stacks and their good solubility makes these flexible disks promising tools for organic electronics. (Figure Presented)
