摘要: In our recently reports, a series of amphipathic β-substituted porphyrins are synthesized, And their LB films show some novel properties.[1] During the preparation of the intermediate of amphipathic porphyrins by the reaction of 2-nitro-5, 10,15,20-tetraphenylporphyrinato copper (Ⅱ) 1 with phenoxide ion 2(eq.l), we found that the product distribution mainly relied on if the electron acceptor was added and which solvent was used. Here we will first report the influence of p-dinitrobenzene (P-DNB) to the above reaction,the influence of the solvents to this reaction and the reaction of 2-naphoxide with 1 will be reported elsewhere.
