Abstract: The treatment of tetrakis(4-pyridyl)porphyrin H2TPyP with a hydrated rare earth (Ⅲ) acetylacetonate RE(acac)3·nH2O (RE=Y, Eu, Gd) in 1,2,4-trichlorobenzene (TCB) pro duced a monomeric porphyrinato rare earth compound RE(TPyP)acac, which further reacted with dicyanobenzene in amyl alcohol in the presence of 1,8-diazabicyclo [5.4.0] undec-7-ene (DBU), giving HRE(TPyP)(Pc) in a good yield. Upon exposure to air, part of the protonated mixed double-deckers in CHCl3 solutions converted slowly to the corresponding neutral complexes RE(TPyP) (Pc). These protonated complexes were characterized by means of UV-Vis, IR, NMR, mass spectroscopies. The quaternarization of these protonated mixed double-deckers with methyl iodide produced the salts of tetramethylated cations [HRE (TMPyP)(Pc)]4+.
