多孔金属有机骨架化合物具有发达的纳米级孔道,其对生物活性气体一氧化氮(NO)的储存和缓释显示出独特的物理与化学性质。目前,基本采用两种方式储存NO,一是通过与材料中的不饱和金属络合,另一是与材料中的氨基形成N-Diazeniumdiolate结构,两种方式储存的NO均可通过水置换反应释放,其缓释动力学受材料的化学组成、孔结构和NO的结合强度影响。本文主要综述了近年来金属有机骨架材料储存和释放NO的研究进展。
Porous metal-organic framework compounds have developed nanoscale pores that exhibit unique physical and chemical properties for the storage and release of the bioactive gas nitric oxide (NO). Currently, there are basically two ways to store NO, one is through the complexation of the unsaturated metal in the material and the other is the formation of an N-Diazeniumdiolate structure with the amino groups in the material, both of which can be released by water displacement reaction The kinetics of sustained release is affected by the chemical composition of the material, the pore structure and the binding strength of NO. This review summarizes the recent progress in the research on the storage and release of NO in metal-organic frameworks.
