Molecular perovskite energetic crystals, as an emerging family of promising practicable energetic materials, have attracted increasing attentions in the past few years. Different from the mainstream strategies focusing on the intra-molecular designs and modifications on fused-ring energetic molecules/ions, molecular perovskites rely on the self-assembly of diverse molecular components into specified ternary crystal structures, hence generally could be prepared via an easy scale-up process at a low cost. As a kind of ternary salts, they have some unique advantages on the energetic-material designs in terms of optimizing oxygen balance, increasing pack efficiency (and crystal density), and decreasing hygroscopicity, hence could achieve improved detonation performances meanwhile overcome some technical weaknesses of traditional energetic binary salts. In this review, we summarize the current findings and understandings on molecular perovskite energetic crystals, and provide an outlook for the new opportunities brought by this new and promising material family towards advanced multi-component energetic crystals.

分子钙钛矿高能晶体，作为有前途的可行高能材料的新兴家族，在过去几年中引起了越来越多的关注。与主要关注分子内设计和对稠环高能分子/离子的修饰的主流策略不同，分子钙钛矿依赖于将各种分子组分自组装成指定的三元晶体结构，因此通常可以通过易于扩展且成本低廉的过程。作为一种三元盐，它们在优化含氧量，提高包装效率（和晶体密度）以及降低吸湿性方面在高能材料设计方面具有一些独特的优势，因此可以改善爆轰性能，同时克服了一些技术上的弱点传统的高能二元盐。在这篇综述中，我们总结了分子钙钛矿高能晶体的最新发现和理解，并展望了这种新的有前途的材料家族为先进的多组分高能晶体带来的新机遇。
