ABX3 perovskites, as the largest family of crystalline materials, have attracted tremendous research interest worldwide due to their versatile multifunctionalities and the intriguing scientific principles underlying them. Their counterparts, antiperovskites (X3 BA), are actually electronically inverted perovskite derivatives, but they are not an ignorable family of functional materials. In fact, inheriting the flexible structural features of perovskites while being rich in cations at X sites, antiperovskites exhibit a diverse array of unconventional physical and chemical properties. However, rather less attention has been paid to these "inverse" analogs, and therefore, a comprehensive review is urgently needed to arouse general concern. Recent advances in novel antiperovskite materials and their exceptional functionalities are summarized, including superionic conductivity, superconductivity, giant magnetoresistance, negative thermal expansion, luminescence, and electrochemical energy conversion. In particular, considering the feasibility of the perovskite structure, a universal strategy for enhancing the performance of or generating new phenomena in antiperovskites is discussed from the perspective of solid-state chemistry. With more research enthusiasm, antiperovskites are highly anticipated to become a rising star family of functional materials.

具有卓越功能的抗钙钛矿。

作为最大的结晶材料家族，ABX3钙钛矿因其多功能的多功能性和深层的科学原理而吸引了全世界的巨大研究兴趣。他们的对应物，抗钙钛矿（X3 BA）实际上是电子反转的钙钛矿衍生物，但它们不是功能性材料的可忽略的家族。实际上，抗钙钛矿继承了钙钛矿的柔性结构特征，同时在X位置上富含阳离子，因此表现出各种非常规的物理和化学特性。但是，对这些“逆向”类似物的关注较少，因此，迫切需要进行全面综述以引起普遍关注。总结了新型抗钙钛矿材料及其卓越功能的最新进展，包括超离子导电性，超导电性，巨大的磁阻，负热膨胀，发光和电化学能量转换。特别地，考虑到钙钛矿结构的可行性，从固态化学的角度讨论了提高钙钛矿性能或在钙钛矿中产生新现象的通用策略。随着研究热情的提高，抗钙钛矿有望成为功能材料的后起之秀。从固态化学的角度讨论了一种提高抗钙钛矿的性能或在抗钙钛矿中产生新现象的通用策略。随着研究热情的提高，抗钙钛矿有望成为功能材料的后起之秀。从固态化学的角度讨论了一种提高抗钙钛矿的性能或在抗钙钛矿中产生新现象的通用策略。随着研究热情的提高，抗钙钛矿有望成为功能材料的后起之秀。
