Abstract: The title compound, C₃₄H₃₂N₄O₂, undergoes a reversible [2+2] photoreaction with 1-(2-benzoxazol-2-yl)-2-bis[4-(dimethylamino)phenyl]ethane (NBE). Through intermolecular head-to-tail [2+2] photocycloaddition of NBE, the title compound displays a centrosymmetric molecular structure in the crystalline state. The cyclobutane ring has an exactly planar conformation and is nearly square.
