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 makes it more and more urgent to develop organic small molecule semiconductors. Based on the unique π-conjugated system of phthalocyanine molecules, high stability and abundant electron level structure of rare earth elements, the rare earth complexes of sandwich type phthalocyanine have many advantages in the field of building field effect transistors. It has turned out that sandwich complexes of rare earth phthalocyanines can be used to create bipolar field effect transistors that have a high mobility for both electron and hole carriers. However, changing the molecular structure of the rare earth complexes of the sandwich type phthalocyanine and the self-assembled nanostructure can all control the characteristics and performance of the molecular semiconductor device formed by the sandwich type phthalocyanine. This article summarizes these very interesting developments in recent times.
