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