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。
In refluxing n-amyl alcohol, DBU (1,8-diazabicyclo [5.4.0] undecene-7) was synthesized using RE (acac) 3 · nH2O (acac = acetylacetone monovalent anion) as a template, As a catalyst, reacted with 4,5-bis (4-methoxyphenoxy) phthalonitrile in refluxing n-amyl alcohol, we synthesized a series of 15 novel rare earth symmetric two-layer complexes M [Pc (MeOPhO) 8] 2 [M = Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu; , 10,16,17,23,24-octa (4-methoxyphenoxy) phthalocyanine]. The entire series of symmetrical two-layer complexes are mainly characterized by means of UV-Vis, IR spectroscopy. All the studies show that there is a strong π-π interaction between the two macrocycles, and the holes are mainly located on the phthalocyanine macrocyclic ligands.
