Electrochemiluminescence of corannulene in acetonitrile by the use of coreactants is reported here for the first time. The investigation has been carried out utilizing both benzoyl peroxide as a sacrificial coreactant and arylamine derivatives as nonsacrificial species to perform mixed-annihilation processes. The electrochemiluminescence produces an intense blue light. The use of different tris(arylamines) as mixed-annihilation coreactants gives rise to exciplexes with corannulene that emit at different wavelengths, thus allowing the emission color to be tuned by changing the coreactant molecule. This opens a potential pathway to exploitation of such an intriguing carbon structure for building efficient blue-light emitting devices.
