摘要:
New perylene chromophores, phenyl-substituted diindeno[1.2.3-cd: 1',2',3'-lm]perylenes 5 a,b and 4.4'.7,7'-tetraphenyldiacenaphtho[1.2-k:1',2',k']diindeno[1,2,3-cd :1'.2'.3'-me]perylenes 22 a,b, have been synthesized from substituted fluoranthene derivatives 3a,b and 4a,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 H-1 and C-13 NMR spectroscopy becomes possible.
