Abstract: High Resolution Image Download MS PowerPoint Slide 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 3 )] n (CMOF-1) and [Ag(ATRZ) 1.5 (ClO 4 )] 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, BrO 3 – and ClO 4 – . 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.
