Developing pure organic room-temperature phosphorescence (RTP) materials remains an enormous challenge, especially for efficient near-infrared (NIR) RTP materials. Herein, a functional unit combination strategy is employed to design a series of pure organic molecules, in which benzo[c][1,2,5]thiadiazole (BZT) serves as the main luminescent core of RTP, while the folded units are responsible for spin–orbit coupling (SOC) enhancement and emission redshift. By integrating both rigid and flexible folded units into the…
