超碱是具有比铯原子低的电离能(IES)的团簇或分子，因此具有良好的还原性能。这种特殊的物种具有巨大的潜力，可用于合成特殊的电荷转移盐和具有定制性质的团簇组装纳米材料，用于二氧化碳的还原，或用作储氢材料和稀有气体捕捉剂等。在这方面，人们一直致力于设计和表征新型超碱。本文从理论设计、表征和潜在应用等方面综述了近年来超碱的研究进展。我们希望这篇综述不仅能为这一研究领域提供一个广泛的概述，而且还能突出进一步扩大超碱的实验合成和实际应用的前景。
Superalkalis are clusters or molecules featuring lower ionization energies (IEs) than that of cesium atoms, and thus exhibit excellent reducing properties. Such special species have great potential to be used in the synthesis of unusual charge-transfer salts and cluster-assembled nanomaterials with tailored properties, in the reduction of carbon dioxide, or as hydrogen storage materials and noble-gas-trapping agents, etc. In this regard, ongoing efforts have been devoted to designing and characterizing superalkalis of new types. The recent progress on the study of superalkalis in terms of theoretical design, characterization, and potential application is summarized in this minireview. We hope this review will not only provide a broad overview of this research field, but also highlight the prospect of further extending the experimental synthesis and practical application of superalkalis.
