(4NPEA)PbI (4NPEA = 4-nitrophenylethylammonium) is the first 3 × 3 corrugated 2D organic-Pb/I perovskite. The nitro groups are involved in cation-cation and cation-iodide interactions. The structure contains both highly distorted and near-ideal PbI octahedra, consistent with the observation of two Pb NMR resonances, while the optical properties resemble those of other 2D perovskites with distorted PbI octahedra.
(4NPEA)PbI（4NPEA = 4-硝基苯乙基铵）是首例 3×3 波纹状二维有机-Pb/I 钙钛矿。硝基参与了阳离子-阳离子和阳离子-碘化物相互作用。该结构同时含有高度扭曲和近乎理想的 PbI 八面体，与观察到的两个 Pb NMR 共振相一致，而光学性质则类似于其他具有扭曲 PbI 八面体的二维钙钛矿。
