Used as a building block in organic semiconductors due to its rigid, planar structure and electron-deficient nature. Commonly applied in the development of high-performance electronic materials such as organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its strong intermolecular interactions enhance charge carrier mobility. Also investigated in fluorescent dyes and sensors for detecting metal ions or biological molecules. Shows potential in conductive polymers and electroactive materials for flexible electronics.
