A series of four amphiphilic heteroleptic tris(phthalocyaninato) europium complexes with different lengths of hydrophobic alkoxy substituents on one outer phthalocyanine ligand [Pc(15C5)4]Eu[Pc(15C5)4]Eu[Pc(OCnH(2n+1))8] (n = 4, 6, 10,12) (1, 2, 4, and 5) was designed and prepared. Their film forming and organic field effect transistor properties have been systematically studied in comparison with analogous [Pc(15C5)4]Eu[Pc(15C5)4]Eu[Pc(OC8H17)8] (3). Experimental results showed that all these typical amphiphilic sandwich triple-decker molecules have been fabricated into highly ordered films by the Langmuir-Blodgett (LB) technique, which displays carrier mobility in the direction parallel to the aromatic phthalocyanine rings in the range of 0.0032-0.60 cm2 V(-1) s(-1) depending on the length of the hydrophobic alkoxy substituents. This is rationalized on the basis of comparative morphology analysis results of the LB films by the atomic force microscopy technique.
设计并制备了一系列四个两亲性异配体三（酞菁基）铕配合物，其中一个外层酞菁配体上带有不同长度的疏水烷氧基取代基[Pc(15C5)4]Eu[Pc(15C5)4]Eu[Pc(OCnH(2n+1))8]（n = 4、6、10、12）（1、2、4和5）。与类似的[Pc(15C5)4]Eu[Pc(15C5)4]Eu[Pc(OC8H17)8]（3）相比，系统研究了它们的成膜和有机场效应晶体管性能。实验结果表明，所有这些典型的两亲性夹心三层分子都通过朗缪尔-布洛杰特（LB）技术制备成了高度有序的薄膜，其在平行于芳香酞菁环方向上的载流子迁移率在0.0032 - 0.60 cm2 V(-1) s(-1)范围内，这取决于疏水烷氧基取代基的长度。这是基于原子力显微镜技术对LB薄膜的比较形态分析结果得出的合理结论。
