Rigid Boron‐Fused Frameworks for Efficient Near‐Infrared Emission and Optical Gain Beyond 900 nm

Advanced Optical Materials, EarlyView.
Multiple‐resonance (MR)‐derived boron‐fused frameworks were integrated into narrow‐gap, long‐range charge‐transfer emitters to reduce structural relaxation and electron‐vibrational coupling. This strategy significantly decreases nonradiative losses, leading to improved near‐infrared (NIR) luminescence efficiency and low‐threshold amplified spontaneous ...
