设计并合成了一系列不同长度疏水取代基的两亲异构型三(酞菁)铕配合物[Pc(15C5)(4)]Eu[Pc(15C5)(4)]Eu[Pc(OCnH2n+1)(8)](n=4，6，10，12)(1，2，4，5)。与类似的[Pc(15C5)(4)]Eu[Pc(15C5)(4)]Eu[Pc(OC8H17)(8)](3)进行了比较，系统地研究了它们的成膜性和有机场效应晶体管的性质。实验结果表明，这些典型的两亲性三明治三层分子均已用朗缪尔-布洛杰特(LB)技术制备成高度有序的薄膜，其载流子迁移率随疏水性烷氧基的长度而变化，在0.0032~0.6 cm(2)V~(-1)S(-1)范围内平行于芳香族酞菁环。根据原子力显微镜对LB膜的比较形貌分析结果，这是合理的。
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(OCnH2n+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 cm(2) 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.
