제목 Design of Indigo Derivatives as Small-Molecule Organic Semiconductors for n-channel Field-Effect Transistors
초록 Rapid technological progress toward the organic electronics field has developed many high-performance small-molecule semiconductors for organic field-effect transistors (OFETs). However, most semiconducting materials have been reported to give unipolar p-channels and p-channel-dominant ambipolar charge transport because n-channel materials, which have high-LUMO energy levels, are usually very reactive in ambient air. Herein, we report on indigo derivatives with strong electron-withdrawing groups which can improve environmental stability in n-channel OFET operations. As well as stability, indigos have attracted great interest due to its flexibility and environment-friendly properties. Therefore organic compounds with indigo backbones, which have very low toxicity and natural occurrence, are expected to apply as biocompatible organic semiconductors.
