Abstract
A hemicurcuminoid boron difluoride complex is used as an emitter in organic light-emitting diodes, showing far red/near-infrared electroluminescence with an external quantum efficiency as high as 2.1%. This dye blended in CBP thin films shows amplified spontaneous emission with a threshold of 22 mu J cm(-2) at 750 nm, making this compound attractive for organic semiconductor lasers operating in the near-infrared region.
