Columnar mesophases are formed by the diskshaped dimers of 6(5 H )‐phenanthridinones 1 (R = n ‐C 8 H 17 , n ‐C 10 H 21 , n ‐C 12 H 25 ). The stacks of self‐organized dimers are packed in a hexagonal arrangement. On cooling from the isotropic phase the growth of the liquid crystal is dendritic, which is typical for the formation of columnar phases.
