Recently, a research team headed by Professor Jiang Yadong of the School of Optoelectronic Science and Engineering, working in tandem with Professor Chi Chun-Yan from the National University of Singapore, has achieved a notable milestone in the realm of short-wave infrared organic semiconductor material synthesis. They have introduced an innovative Lewis acid-catalyzed condensation technique, which facilitates the streamlined and efficient creation of ultra-narrow bandgap organic semiconductor materials featuring a symmetric quinoid-terminated structure. This significant achievement overcomes a long-standing, half-century-old synthetic hurdle linked to this particular structural form, paving the way for the development of cutting-edge organic short-wave infrared detection materials.
