Modification Of Tetraarylporphyrins At β And Aryl Position

In this thesis, it mainly explores the field of the modification of tetraaryl-porphyrins atβand aryl position. This thesis consists of tow parts:modification of tetraarylporphyrins atβposition and functional group substitution at aryl ring.43 compounds were synthesized in the thesis and 30 of them are new. All the compounds were characterized by 1H NMR, MS, IR and UV-vis spectra. Part 1:p-modification of tetraarylporphyrinsTetraphenylporphyrin was synthetized by using improved Adler-Longo method. In this part, we focused on theβ-modification of tetraarylporphyrins, including metallization, formylation, reduction reaction, condensation reaction with dipeptides. A. series of theβ-modified tetraarylporphyrin derivatives were obtained and characterized. Part 2:Aryl-modification of tetraarylporphyrinsIn this part, the aryl-modification of tetraarylporphyrins was discussed. The syntheses of a series of aryl-modified derivatives of tetraarylporphyrins was carried out by using tetraphenylporphyrin as starting material, including nitration reaction, reduction reaction, condensation reaction with dipeptides and metallization;Specially, the substrate 5-(2-hydroxyphenyl)-10,15,20-tri(4-chlorophenyl)porphyrin was syn-thesized and condensated with dipeptides, and then the functionalized porphyrins were metallized with Mn(Ⅱ) or Zn(Ⅱ) to form miscellaneous porphyrins.
