Extensive (electron) delocalization in the novel heteromolecular pi-complex of the hindered naphthalene cation radical (OMN(+)(*)) with naphthalene (NAP) accompanies the pronounced charge-transfer absorption band at approximately 1100 nm in the near-IR. X-ray crystallography establishes the viability of the unusual "club sandwich" structure despite the repulsive electrostatic forces inherent to the dicationic unit.
受阻萘阳离子自由基（OMN(+)(*)）与萘（NAP）形成的新型异分子π-配合物中存在广泛的（电子）离域，伴随着近红外区约1100 nm处明显的电荷转移吸收带。X射线晶体学证实了这种不寻常的“棒状三明治”结构的可行性，尽管二价阳离子单元存在固有的静电斥力。
