Condensation of two equivalents of an aromatic cyclic anhydride with an aromatic diamine, or of two equivalents of an aromatic amine with an aromatic bisanhydride, results in the formation of an aromatic bisimide. Thirty‐one such bisimides were prepared. The bisimides in which the two imide groups arc connected by a fully coplanar system show extremely low solubilities and high melting and decomposition temperatures. Many are also strongly colored. It is suggested that these properties may result from intermolecular charge‐transfer effects in the solid slate, giving charge‐transfer polymers.
