Oxygen-responsive high-efficiency orange-red room-temperature phosphorescence from chalcogen-containing dibenzo[a,c]phenazine foldamers
Efficient orange-red/red room-temperature phosphorescence (RTP) in purely organic materials is highly desirable for bio-imaging and information security but remains scarce due to the energy gap law and the challenge in achieving strong spin–orbit coupling (SOC) in red-emitting systems. Herein, a functional unit combina...
