Abstract We report the investigation on the nonlinear optical properties of two typical two-dimensional metal-organicframeworks (2D MOFs) - 2D Cu-MOF and Zn-MOF ( c opper/zinc 1,4-benzene dicarboxylate, CuBDC and ZnBDC) using spatial self-phase modulation (SSPM) and spatial cross-phase modulation (SXPM) methods. It is found that 2D Cu-MOF exhibits a large nonlinear optical coefficient n 2 = 5.20 × 10 -

Two Zn-based metal-organic frameworks (Zn-MOFs) were solvothermally synthesized using two pyridine-based carboxylate linkers to generate unique pore topologies, as evidenced by single-crystal XRD analysis. These Zn-MOFs provided coordinatively unsaturated Zn2+ sites with square-pyramidal geometry, leading to an enhanced interaction with CO2, as demonstrated by sub-atmospheric pressure isotherms. The
使用两种基于吡啶的羧酸盐接头溶剂热合成了两种基于锌的金属有机骨架 (Zn-MOF),以产生独特的孔拓扑,如单晶 XRD 分析所证明的那样。这些 Zn-MOF 提供了具有方形锥体几何形状的配位不饱和 Zn2+ 位点,从而增强了与 CO2 的相互作用,如亚大气压等温线所示。在大气 CO2 下通过拉曼光谱验证了这些 MOF 中开放 Zn2+ 位点的存在,揭示了 CO2 化学吸附在表面位点上的存在。此外,与仅显示物理吸附乙酸物质的 IRMOF-1 相比,化学吸附乙酸的原位 DRIFT 光谱为吸附后形成乙酸-Zn2+ 物质提供了证据。

The present invention relates to a novel class of shaped bodies containing metal-organic frameworks. Said metal-organic frameworks comprise at least one metal ion and at least one at least bidentate organic compound and contain at least one type of micro- and mesopores or micro- or mesopores. Said shaped bodies comprise at least one metal-organic framework material and may optionally contain further substances, in particular at least one supporting material.
