Low-dimensional inorganic–organic hybrid perovskites with high moisture tolerance and long-lived charge separation states have captured significant attention in the field of optoelectronic devices. To further achieve the relationship between crystal structures and stability, as well as charge separation behaviors, three one-dimensional hybrid perovskites containing electron-deficient naphthalene diimide ammonium (NDIEA) and electron-rich iodoplumbate chains, [(H₂NDIEA)Pb₂I₆]·2DMF (1), [(H₂NDIEA)₂Pb₅I₁₄·(DMF)₂]·4DMF (2), and [(HNDIEA)₂Pb₂I₆]·3H₂O (3), were synthesized. Crystal structure determinations revealed various synthesis conditions leading to different stacking modes, especially the inorganic lead iodide fraction, which resulted in different water resistances and charge-separated behaviors. The comprehensive analysis found that strong intermolecular interactions (anion−π interactions and π–π interactions), and matching energy levels between protonated NDIEA and iodoplumbate chains, can facilitate the generation of long-lived charge separation states and extraordinary moisture stability, even in the water environment. In addition, the conductivity behavior of 3 was also explored in detail.

具有高耐湿性和长寿命电荷分离状态的三种半导体一维萘二亚胺/碘铅酸钙钛矿

具有高耐湿性和长寿命电荷分离状态的低维无机-有机杂化钙钛矿在光电器件领域引起了广泛关注。为了进一步了解晶体结构与稳定性以及电荷分离行为之间的关系，含有缺电子萘二亚胺铵（NDIEA）和富电子碘铅酸链的三种一维杂化钙钛矿，[（H 2 NDIEA _） Pb ₂ I ₆ ]·2DMF ( 1 ), [(H ₂ NDIEA) ₂ Pb ₅ I ₁₄ ·(DMF) ₂ ]·4DMF ( 2 ), [(HNDIEA) ₂ Pb ₂I ₆ ]·3H ₂ O ( 3 ), 被合成。晶体结构测定揭示了导致不同堆积模式的各种合成条件，尤其是无机碘化铅部分，这导致了不同的耐水性和电荷分离行为。综合分析发现，强分子间相互作用（阴离子-π相互作用和π-π相互作用）以及质子化NDIEA和碘铅酸链之间的匹配能级，可以促进长寿命电荷分离态和非凡水分稳定性的产生，即使在水环境。此外，还详细探讨了3的导电行为。
