J. Mizuguchi and H. Shiozaki

Abstract: The title compound, C₁₈H₂₄N₂O₄, is an aminonaphthoquinone derivative that exhibits a large third-order non-linear optical susceptibility. The centrosymmetric naphthoquinone moieties are connected by bifurcated N-HO hydrogen bonds to form a ribbon structure along [10]. The molecules are stacked along the c axis, with overlap occurring only at the periphery of the naphthoquinone skeleton.
