Abstract

In this study, we demonstrate the targeted insertion of additional Cu(II) into a hydrogen-bonded metal–organic framework, HMOF(Cu-atrz-nt), thereby achieving the in-situ modulation of hydrogen bonds (HBs) into coordination bonds (CBs) with virtually no alteration to the framework structure, converting HMOF(Cu-atrz-nt) into a purely coordinated MOF(Cu-atrz-nt). Significantly different from classical MOF-5 and ZIF-8, HMOF(Cu-atrz-nt) and MOF(Cu-atrz-nt) exhibit markedly stronger exothermicity along with truncated HB and CB characteristics and electronic properties, showing outstanding but distinct catalytic combustion effects on key propellant components such as RDX, HMX, CL-20, and AP. This study aims to enhance the comprehension of the weak interactions of framework materials while uncovering novel and exciting prospects for practical applications.

氢键金属-有机骨架（HMOF）内弱相互作用的原位调制用于优质推进剂的应用

在这项研究中，我们展示了将额外的Cu（II）定向插入到氢键金属有机框架HMOF（Cu-atrz-nt）中，从而实现了氢键（HBs）的原位调制成配位键（CBs），而几乎没有改变框架结构，将HMOF（Cu-atrz-nt）转化为纯配位的MOF（Cu-atrz-nt）。与传统的MOF-5和ZIF-8不同，HMOF（Cu-atrz-nt）和MOF（Cu-atrz-nt）表现出更强的放热性、截断HB和CB特性和电子性能，对RDX、HMX、CL-20和AP等关键推进剂组分具有明显的催化燃烧作用。本研究旨在增强对框架材料弱相互作用的理解，同时揭示新的和令人兴奋的实际应用前景。
