摘　　要：信息科技的高速发展使得开发有机小分子半导体越来越成为迫切的现实需求。而基于酞菁分子独特的π共轭体系,超高的稳定性以及稀土元素丰富的电子能级结构,三明治型酞菁的稀土配合物在构建场效应晶体管方面具有很多优势。事实证明,三明治型酞菁的稀土配合物可以用来构建双极性场效应晶体管,其对电子和空穴载流子都有很高的迁移率。而改变三明治型酞菁的稀土配合物的分子结构和自组装纳米结构都可以调控其所形成的分子半导体器件的特点和性能。本文对近期这些非常有意义的研究进展进行了总结。The rapid development of information technology promotes the requirements of high-speed computing.Therefore,organic transistors based on small molecular weight materials are attracting more and more interests recently. Depending on the special π conjugated systems and nice stability of phthalocyanine molecules,as well as the interesting energy levels and electronic structures of rare earth elements,sandwich-type phthalocyanine rare earth complexes can be very good candidates for constructing field-effect transistor. Actually,the organic fieldeffect transistors devices fabricated from sandwich-type phthalocyanine rare earth complexes show high and balanced ambipolar performance with high mobilities for both holes and electrons. And the properties of these devices can be modulated by changing the molecular structures or the self-assembled nanostructures of these systems. This manuscript will briefly summarize the progress achieved in this research field recently.
