由配合物作前驱体(简称:前驱体配合物)来制备子代配合物是配合物定向合成的有效方法之一。与一般的有机配体相比,前驱体配合物拥有特定的、相对稳定的结构骨架,并且在一定的反应条件下能够与有机配体之间进行定向自组装,形成具有预期结构的配合物,同时还能把自己的结构特征“遗传”给子代配合物。本论文选择一个一维长链铜配合物{[Cu(bbbm)(CH_3COO)_2]·(CH_3OH)_2}n(Q)[bbbm=1,1’-(1,4-丁基)-二-(1-H-苯并咪唑)]作为前驱体配合物,通过小分子配体的取代、加成反应获得了一个新的子代配合物[Cu(bbbm)(N_3)_2(Py)]n(1)。单晶衍射分析结果显示子代配合物(1)“遗传”了前驱体配合物(Q)的一维长链结构。我们还进一步研究了反应前后配合物的配位方式、bbbm配体构象变化及其催化性能变化。
It is one of the most effective methods for the targeted synthesis of complexes by using complex as precursors (abbreviation: precursor complexes) to prepare daughter complexes. Compared with the general organic ligands, the precursor complexes have a specific, relatively stable structural framework, and under certain reaction conditions can be directed to self-assembly with organic ligands to form a complex with the desired structure, At the same time can also own structural features “genetic ” to offspring complexes. In this thesis, a one-dimensional long-chain copper complex {[Cu (bbbm) (CH_3COO) _2] · (CH_3OH) _2} n (Q) [bbbm = 1,1 ’- (1,4-butyl) - (1-H-benzimidazole)] as a precursor complex, a new daughter complex [Cu (bbbm) (N_3) _2 (Py)] was obtained through the substitution and addition of small molecule ligands n (1). Single crystal diffraction analysis showed that the daughter complex (1) “inherited ” one-dimensional long chain structure of the precursor complex (Q). We also further studied the coordination mode before and after the ligand, bbbm ligand conformational changes and changes in their catalytic properties.
