Treatment of the dimer of 2‐arylphenanthro[9,10‐ d ]imidazoles with nucleophilic compounds such as alcohols, aliphatic amines, and carboxylic acids afforded 2‐substituted‐2 H ‐ and 4‐substituted‐4 H ‐2‐arylphenanthro[9,10‐ d ]isoimidazoles. These products showed a characteristic photochromism by dissociation to a stable imidazolyl radical.
