abstract
- Bright blue light with a maximum at 450 nm is emitted by both structural isomers of the novel, stable BIII2 (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 Cs symmetry) and electroluminesces when used as the emitting layer in an electroluminescent device.
