Crystal structure and properties of new benzimidazopyrido[2,3-b]indole-6-carbonitriles

The structure of representatives of a new heterocyclic system, 12H-benzimidazo[1',2':1,6]pyrido[2,3-b]indole-6-carbonitriles, potential bioactive compounds, is elucidated by X-ray diffraction. The compounds exhibit luminescence in the blue region of the spectrum with quantum yields close to unity, which makes them promising phosphors for application in modern emitting devices.
