Recently, organic-inorganic hybrids materials have been researchers’ interest due to their tunable structure and switching physical properties. Solid-state hybrid materials are very promising in the field for fundamental and applied sciences.I prepared halogen-bridged 1D Pd/Pt chain complexes (MX-chain) as multifunctional materials. Pd and Pt-based MX-chain complexes usually show M(II)/M(IV) mixed-valance (MV) state due to the small on-site coulomb repulsion. I developed new method for realize uncommon Pd(III) AV state, [Pd(dabdOH)2Br]Br2 (dabdOH =(2S,3S)-2,3-diaminobutane-1,4-diol), so-called "multiple-hydogen-bond” approach (J. Am. Chem. Soc. 2017, 39, 6562). Electronic state Pt ions are in MV state using same strategy. However, this method is very promising for shortening metal-metal distance, resulting good conducting materials (Inorg. Chem, 2019, 58, 114). Moreover, this method is also applicable for large size counters anion. Pd(III) ions was isolated with sulfate ions via this method (CryEngComm, 2020, Submitted).Currently, I extended my work into two or three-dimensional (2D or 3D) hybrid materials (MOFs). I was able to growth and control copper nano particle (CuNPs) size into MOFs. For example, NU-901 and NU-907, with distinct pore diameters that serve as templates for the controlled growth of CuNPs of different sizes (~1.5 nm and ~0.9 nm, respectively). These MOF-supported CuNPs were shown to be competent catalysts for selective acetylene semihydrogenation with a TOF of 13.5 and 7.7 h-1, respectively (Chem. Mat. 2020, 10.1021/acs.chemmater.0c00059).

近年来，有机-无机杂化材料由于其结构可调、物理性能可调等特点，引起了人们的广泛关注。固态杂化材料在基础科学和应用科学领域都有着广阔的应用前景，本文制备了卤素桥联的一维Pd/Pt链状配合物（MX-链）。Pd和Pt基MX链配合物由于在位库仑排斥小，通常表现为M（II）/M（IV）混合价态。我发展了一种实现Pd（III）AV态的新方法，[Pd（dabdOH）2Br] Br 2（dabdOH =（2S，3S）-2，3-diaminodutane-1，4-diol），即所谓的“多氢键”方法（J. Am. 2017，39，6562）。电子态Pt离子使用相同的策略处于MV态。然而，这种方法非常有希望缩短金属-金属距离，从而产生良好的导电材料（Inorg. Chem，2019，58，114）。该方法也适用于大型阴离子计数器。通过这种方法将Pd（III）离子与硫酸根离子分离（CryEngComm，2020，Submitted）。目前，我将我的工作扩展到二维或三维（2D或3D）杂化材料（MOFs）。我能够生长和控制铜纳米颗粒（CuNPs）的大小到MOF中。例如，NU-901和NU-907，具有不同的孔径，用作不同尺寸（分别为~1.5 nm和~0.9 nm）的CuNP的受控生长的模板。这些MOF负载的CuNP显示为分别具有13.5和7.7h-1的TOF的选择性乙炔半氢化的胜任催化剂（Chem.Mat.Chem.Sci. 0c00059）。
