| 摘要: 在回流的正戊醇中，以RE(acac)3·nH2O (acac=乙酰丙酮一价阴离子)为模板，以DBU(1，8-二氮杂双环[5.4.0]十一烯-7)作催化剂，在回流的正戊醇中与4，5-二(4-甲氧苯氧基)邻苯二甲氰反应，我们合成了一系列的15个新型稀土对称二层配合物M[Pc(MeOPhO)8]2[M=Y，La，Ce，Pr，Nd，Sm，Eu，Gd，Tb，Dy，Ho，Er，Tm，Yb，Lu；H2Pc(MeOPhO)8=2，3，9，10，16，17，23，24-八(4-甲氧苯氧基)酞菁]。整个系列的对称二层配合物主要借助于UV-Vis，IR谱学手段得到充分的表征。所有的研究表明在两个大环之间存在强烈的π-π相互作用，空穴主要位于酞菁大环配体上。 |

| Abstract: 15 rare earth double-deckers M[Pc(MeOPhO)8]2 [M=Y, La … Lu, except Pm; H2Pc=2, 3, 9, 10, 16, 17, 23, 24-octakis(4-methoxyphenoxy)phthalocyanine] have been prepared by treating RE(acac)3·nH2O (acac=acetylacetonate) with 4,5-bis(4-methoxy)phenoxyphthalonitrile in refluxing 1-pentanol in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU). The phthalonitrile with the 4-methoxyphenoxy derivative, a precursor of the phthalocyanine, was synthesized by nucleophilic addition of 4, 5-dichlorophthalonitrile with 4-methoxyphenol in dry DMSO solution. These novel sandwich-type complexes have been characterized by UV-visable and Infra-red spectroscopy. The results indicate that there are substantial π-π interactions and the hole mainly locates at the Pc ligands. |
