摘要
基于有机半导体材料的薄膜器件包括有机薄膜晶体管(OTFTs)、有机发光二极管(OLEDs)、有机光伏器件(OPV)和有机电致变色器件(OEC)等引起了学术界和工业界的极大兴趣。有机半导体材料的性质直接取决于其分子结构。介绍了如何通过对分子的侧链设计获得一系列具有独特性能的有机半导体材料,以及它们在OTFTs、OEC及有机无机钙钛矿太阳能电池空穴传输层中的应用。作为有机薄膜场效应晶体管的活性层,这些有机半导体材料不仅显示高迁移率,其溶液和固体膜还展现出高荧光量子效率。
Abstract
Organic electronics based on the thin film devices, including organic thin film transistors (OTFTs), organic photovoltaics (OPVs) and organic electrochromic devices (OECs) are envisioned both great interest in academia and industry.The properties of organic semiconductor materials are directly governed by the molecule structures. This paper will present the recent work conducted in our labs for molecule design strategies. Examples include strategies for searching high mobility organic semiconductors with unique properties for OTFT applications, series of organic semiconductors with hetero atom substituted side chains in the main backbone of phenyl-anthracene have been synthesized, characterized and are used as active layers in the thin film organic field effect transistors (OFETs). All the semiconductors not only show high charge mobility, but also demonstrate high fluorescent quantum efficiency both in solution and solid films. Interesting results will be discussed.
