Abstract

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