An azulene derivative possessing a diphenylphosphoryl and an amino group at the 2- and 6-positions, respectively, was synthesized. The X-ray structure analysis of this compound revealed that the bond alternation of the azulenyl skeleton appears clearly. This shows that the contribution of a quinoid structure is pronounced. The phosphoryl group is linked to the amino group by intermolecular hydrogen bonding to form an infinite chain structure.

合成了一种在2-位和6-位分别含有二苯基磷基和氨基的天青烯衍生物。X-射线结构分析表明，该化合物的天青基骨架发生了明显的成键变化。这表明，喹类结构的贡献是显著的。磷酰基通过分子间氢键与氨基相连，形成无限大的链状结构。
