In the title compound, C29H20N2, the dihedral angles subtended by the central p-phenyl-enedi-amine ring with respect to the mean plane of the terminal pyrenyl ring system (r.m.s. deviation = 0.027 Å) and the terminal N-phenyl ring are 29.34 (4) and 43.43 (7)°, respectively. The conformation about the C=N bond is E. In the crystal, mol-ecules are linked by N-H⋯π and C-H⋯π inter-actions forming chains propagating along the [10-2] direction. These chains are linked via π-π inter-actions [inter-centroid distances are in the range 3.5569 (11)-3.708 (1) Å], forming slabs lying parallel to (30-4).
在标题化合物C₂₉H₂₀N₂中，中心对苯二胺环相对于末端芘基环系统平均平面（均方根偏差 = 0.027 Å）和末端N-苯基环所形成的二面角分别为29.34 (4)°和43.43 (7)°。C=N键的构象为E型。在晶体中，分子通过N-H⋯π和C-H⋯π相互作用连接，形成沿[10 -2]方向延伸的链。这些链通过π-π相互作用相连[质心间距离在3.5569 (11)-3.708 (1) Å范围内]，形成平行于(30 -4)的片层。
