Lithiation and subsequent formylation of bromo-substituted tetraarylporphyrins 3a-d, prepared under Adler-Rothemund conditions, afford a mixture of the porphyrinylbenzaldehydes 4a-d and the corresponding dialdehydes (cis and trans isomer) 7a/7d and 8a/8d, which may be isolated by column chromatography.The readily available porphyrins are suitable precursors for the synthesis of oligoporphyrinyl systems which is demonstrated for the case of the novel stilbene-linked diporphyrinyl 12.Alkyl substitution of the nonfunctionalized aryl groups brings about sufficient solubility of the porphyrins in organic solvents.
