Indigoid compounds which absorb light with as long a wavelength as possible are an attractive synthetic goal, since they are potential materials for optical data storage. In this report the synthesis of homologues of indigoid compounds with para ‐quinodimethane units are described; compounds like 1 absorb at wavelengths considerably longer than those of the related vinylogues.
