1D perovskite micro/nanocrystals (1D PMCs) have captured the interest of scientists because they have fascinating properties and many potential technological applications. In comparison to polycrystalline perovskite films, 1D PMCs with well‐defined crystal structures possess larger carrier mobilities, higher photoluminescence quantum yields, and longer carrier diffusion lengths, making them an attractive system for both fundamental research and device applications. Here, recent developments in the controllable fabrication of 1D PMCs with excellent optoelectronic properties are described. Special attention is paid to methods for the aligned/patterned assembly of 1D PMCs, including evaporation‐induced self‐assembly, meniscus‐assisted self‐assembly, confinement self‐assembly, and template‐guided self‐assembly methods. Recent progress in the use of 1D PMCs in photodetectors, lasers, light‐emitting diodes, and solar cells is also reviewed. Finally, the challenges and outlook of 1D PMCs in future device applications are presented.

一维有机-无机杂化钙钛矿微/纳米晶体：制造，组装和光电应用

一维钙钛矿微/纳米晶体（1D PMC）吸引了科学家的兴趣，因为它们具有令人着迷的特性和许多潜在的技术应用。与多晶钙钛矿薄膜相比，具有明确晶体结构的一维PMC具有更大的载流子迁移率，更高的光致发光量子产率和更长的载流子扩散长度，这使其成为基础研究和器件应用的有吸引力的系统。在此，描述了可控制造具有优异光电性能的一维PMC的最新进展。一维PMC的对齐/图案组装方法应特别注意，包括蒸发诱导自组装，弯月面辅助自组装，约束自组装和模板引导自组装方法。还回顾了在光电探测器，激光器，发光二极管和太阳能电池中使用一维PMC的最新进展。最后，介绍了一维PMC在未来设备应用中的挑战和前景。
