New perylene chromophores, phenyl-substituted diindeno[1,2,3-cd: 1′,2′,3′-lm]perylenes 5a,b and 4,4′,7,7′-tetraphenyldiacenaphtho[1,2- k:1′,2′,k′]diindeno[1,2,3-cd:1′,2′,3′- me]perylenes 22a,b, have been synthesized from substituted fluoranthene derivatives 3 a,b and 4 a,b by means of a surprisingly simple oxidative cyclodehydrogenation reaction. The resulting chromophores, when substituted with alkyl chains at the periphery, show good solubility in organic solvents, and a full characterization of the novel red, green, and blue dyes by field-desorption mass spectrometry, UV/Vis and ¹H and ¹³C NMR spectroscopy becomes possible.
