摘要：

The naphthalene dication 3 is appreciably more unstable than the ethene and benzene analogues 1 and 2, respectively. This was revealed by oxidation experiments with 2,3,6,7‐tetrakis(dimethylamino)naphthalene. Apparently, the bi‐cyclic framework of 3 is so strongly planarized that a planar arrangement of the mesomeric cyanine systems is hindered by steric interaction between the neigh‐boring NMe2 groups.
