The synthesis of four shape‐persistent macrocycles with three 1,8‐diazaanthracene units each is reported (2,3 a–3 c). For two of them singlecrystals could be obtained and the structures in the crystal be solved. The structures reveal that macrocycle 2 self‐dimerizes in the solid state; surprisingly it also forms a stable dimer in solution. The reason for this is seen in unusually efficient dispersion
