Abstract

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)(BrO₃)]_n (CMOF-1) and [Ag(ATRZ)_1.5(ClO₄)]_n (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, BrO₃ ^- and ClO₄ ^-. 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.

金属-有机框架的主客体协同作用增强近红外超快激光响应性。

主客体金属有机框架（mof）在调节和优化新型材料性能和功能方面具有巨大的潜力和价值，这是由于主客体框架和客体单元之间的协同效应。本研究报道了两种银基主客体mof [Ag(ATRZ)(BrO3)]n （CMOF-1）和[Ag(ATRZ)1.5(ClO4)]n （CMOF-2）作为激光响应材料的候选材料。这些材料分别具有1D和3D结构，由Ag-ATRZ阳离子MOF框架和两种不同的氧化阴离子客体BrO3 -和ClO4 -组成。CMOF-1和CMOF-2是通过简单、环保的方法合成的，可以快速制造。CMOF-1和CMOF-2优异的近红外（NIR）激光响应性是通过调制阳离子mof （CMOFs）结构和主客体组分之间的协同相互作用实现的。此外，两者都表现出超快的爆燃-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，为开发高性能激光响应材料提供了有效的策略。
