Abstract

Bright blue light with a maximum at 450 nm is emitted by both structural isomers of the novel, stable B^III₂ (O)(7-azain)₂ Ph₂ (7-azain=7-azaindole anion) on irradiation with UV light. The isomer shown in the picture has approximate C₂ symmetry (the other isomer approximate C_s symmetry) and electroluminesces when used as the emitting layer in an electroluminescent device.
