Host-guest metal-organic frameworks (MOFs) offer significant potential and value in regulating and optimizing novel material properties and functionalities, owing to the synergistic effects between the host framework and the guest units. This study reported two silver-based host-guest MOFs, [Ag(ATRZ)(BrO)] (CMOF-1) and [Ag(ATRZ)(ClO)] (CMOF-2), as promising candidates for laser-responsive materials. These materials feature 1D and 3D structures, respectively, comprising Ag-ATRZ cationic MOF frameworks integrated with two distinct oxidizing anionic guests, BrO and ClO . CMOF-1 and CMOF-2 are synthesized through straightforward, environmentally benign methods, enabling rapid fabrication. The exceptional near-infrared (NIR) laser responsiveness of CMOF-1 and CMOF-2 was achieved through the modulation of the cationic MOFs (CMOFs) architectures and synergistic interactions between the host and guest components. Moreover, both exhibit ultrafast deflagration-to-detonation transition (DDT) capabilities, alongside excellent thermal stability. This work expands the application scope of host-guest MOFs, and provides an effective strategy for developing high-performance laser-responsive materials.
由于主体框架与客体单元之间的协同效应，主客体金属有机框架（MOF）在调节和优化新型材料的性能与功能方面具有巨大潜力和价值。本研究报道了两种银基主客体MOF，即[Ag(ATRZ)(BrO)]（CMOF - 1）和[Ag(ATRZ)(ClO)]（CMOF - 2），它们有望成为激光响应材料。这些材料分别具有一维和三维结构，由与两种不同氧化性阴离子客体BrO 和ClO 整合的Ag - ATRZ阳离子MOF框架组成。CMOF - 1和CMOF - 2通过简单、环境友好的方法合成，能够快速制备。通过调节阳离子MOF（CMOF）结构以及主体和客体组分之间的协同相互作用，实现了CMOF - 1和CMOF - 2出色的近红外（NIR）激光响应性。此外，两者都表现出超快的爆燃转爆轰过渡（DDT）能力以及出色的热稳定性。这项工作拓展了主客体MOF的应用范围，并为开发高性能激光响应材料提供了有效策略。
