Near-infrared organic light-emitting materials, devices and applications

Abstract

Near-infrared (NIR) light-emitting devices have recently garnered significant interest for integration in various applications, including photodynamic therapy and component determination, with emission wavelengths ranging from 700 nm to 2500 nm. In this review, we first introduce molecular design strategies for NIR materials, with a focus on fluorescent, phosphorescent, and TADF materials, and summarize recent advancements in highly luminescent NIR materials. Secondly, we provide an overview of high-performing NIR organic light-emitting devices (OLEDs), examining their structural designs and underlying device physics. Thirdly, we highlight practical applications of NIR materials and OLEDs in areas such as biomedicine and component determination. Finally, we discuss current limitations and prospects for the development of NIR materials, devices, and applications.
