Abstract

The design of organic molecules-based devices with higher charge carrier mobility requires an in-depth understanding of elementary processes relevant to transport of charge carriers in organic thin films. Carrier mobility is large if there is a significant overlap between the molecular orbitals. Here, the exact role of chemical structure and arrangement of molecules in their crystal structure on the performance of metal-free (H2Pc)- and metal phthalocyanines (ZnPc, CuPc and F16CuPc)-based organic thin film transistors (OEFTs) has been observed by a combined experimental and theoretical study.

在有机薄膜晶体管中,是什么决定了小分子有机半导体的迁移率?
设计具有更高载流子迁移率的基于有机分子的器件需要深入了解与有机薄膜中载流子迁移相关的基本过程。如果分子轨道之间有明显的重叠,载流子迁移率就很大。本文通过实验与理论相结合的研究方法,观察了无金属(H2Pc)-和金属酞菁(ZnPc, CuPc和F16CuPc)基有机薄膜晶体管(OEFTs)的化学结构和分子排列对其性能的确切影响。
