The synthesis of a new molecule, SFIC‐Cl, is reported, which features enhanced π‐electron delocalization by spiroconjugation and narrowed bandgap by chlorination. SFIC‐Cl is integrated into a single‐crystal transistor (OFET) and organic light‐emitting diode (OLED). The material demonstrates remarkable transport abilities across various solution‐processed OFETs and retains efficient radiance in a near‐infrared OLED emitting light at 700 nm. Furthermore, the intermolecular multi‐dimensional connection of SFIC‐Cl enables the fabrication of a single‐component large‐area (2 × 2 cm 2 ) near‐infrared OLED by spin‐coating. The SFIC‐Cl‐acceptor‐based solar cell shows excellent power conversion efficiency of 10.16% resulting from the broadened and strong absorption and well‐matched energy levels. The study demonstrates that chlorinated spiroconjugated fused systems offer a novel direction toward the development of high‐performance organic semiconductor materials for hybrid organic electronic devices.
