几十年来，人们一直在研究氧化物钙钛矿的氧化学，揭示了氧阴离子的反应性、输运和电子性质。类似地，卤化物阴离子决定了在卤化物钙钛矿中观察到的性质和不寻常的现象。在一系列光电子技术中，操纵卤化物位置已经改善了卤化物钙钛矿的性能和稳定性，最常见的是作为太阳能电池和发光二极管的组件。此外，卤化物的氧化还原活性允许受控的电子掺杂和卤化物交换，以及捕获和分离卤素气体。在这里，我们总结了钙钛矿型卤化物位化学的关键方面。最后，我们讨论了类卤化物钙钛矿，它与卤化物钙钛矿具有共性。
The oxygen chemistry of oxide perovskites has been studied for decades, revealing reactivity, transport, and electronic properties enabled by the oxide anion. Similarly, the halide anion dictates the properties and unusual phenomena observed in halide perovskites. Manipulating the halide site has improved the performance and stability of halide perovskites in a range of optoelectronic technologies, most commonly as components in solar cells and light-emitting diodes. Further, the redox activity of the halides allows for controlled electronic doping and halide exchange, as well as for the capture and separation of halogen gases. Herein, we summarize the key aspects of the chemistry of the perovskite halide site. We close with a discussion of pseudohalide perovskites, which hold commonalities with the halide perovskites.
