The title quinarenone 2 has a pronounced contribution of the dipolar resonance structure to the ground state, and the three-membered ring of 2 is more diatropic than that of diphenylcyclopropenone.The quinarenone 2 exists in equilibrium with its oligomer in solution.The excited state properties of 2 have also been described.
