混合连接剂金属有机框架（MOFs）在孔结构和表面化学方面都提供了很好的可调性。本研究报告了模型混合连接体M0 F（即，Cu-TMA/Cu-BDC; BDC = 1，4-苯二酸，TMA =均苯三酸），以揭示混合连接剂MOF的性质与组分组成之间的关系。所制备的混合连接剂的MOFs表现出不同的性能方面的形态，晶相，表面化学，和孔结构。特别地，进行二维相关光谱（2D-COS）分析以分析表面官能团之间的相关性特征，这是传统红外和拉曼光谱无法获得的。来自2D-COS分析的结果还表明，通过控制前体条件可以调节混合连接体M0 F的表面化学。CO2吸附的测量混合链接MOFs证明金枪鱼。
Mixed-linker metal–organic frameworks (MOFs) offer great tunability in both pore structures and surface chemistry. This study reports the synthesis and characterization of model mixed-linker MOFs (i.e., Cu-TMA/Cu-BDC; BDC = 1,4-benzenedioic acid, TMA = trimesic acid) via a microdroplet-based spray process, to unravel the relationship between the properties of mixed-linker MOFs and the component compositions. The as-prepared mixed-linker MOFs exhibited distinct properties in terms of morphology, crystalline phase, surface chemistry, and pore structure. In particular, two-dimensional correlation spectroscopy (2D-COS) analysis was conducted to analyze the correlational features among surface functional groups, which are unattainable from traditional infrared and Raman spectra. The results from the 2D-COS analysis also suggest that the surface chemistry of the mixed-linker MOFs is adjustable by controlling the precursor conditions. Measurements of CO2 adsorption on the mixed-linker MOFs demonstrated the tunab...
