合成了配体N,N’-双(8-喹啉基)丙二酰胺(qmaH_2),N,N’-双(2-羟基苯基)丙二酰胺(hpmaH_4)及其金属配合物[M=Cu(Ⅱ)、Ni(Ⅱ)、Co(Ⅲ)、Pd(Ⅱ)、Zn(Ⅱ)]。并采用元素分析,’HNMR、UV-vis、IR、MS、摩尔电导、熔点测定进行了化合物的结构表征对配体qmaH_2的金属配合物作了荧光测定。结果表明:配体hpmaH_4与Cu(Ⅱ)和Co(Ⅱ)配位时,酰胺分别非去质子化和去质子化;配体qmaH_2与金属离子生成类芳香性配合物。由于金属d电子参与芳环π电子的共轭,表现出芳环紫外吸收峰蓝移和荧光性质,尤以Zn(Ⅱ)配合物最佳;配体qmaH_2与Co(Ⅱ)配位时表现出吸氧特性,生成μ-过氧键配合物。
The ligands of N, N’-bis (8-quinolyl) malonamide (qmaH_2), N, N’-bis (2-hydroxyphenyl) malonamide (hpmaH_4) and their metal complexes [M = Cu (II), Ni (II), Co (III), Pd (II), Zn (II)]. The metal complex of qmaH_2 was determined by elemental analysis, structural characterization of ’HNMR, UV-vis, IR, MS, molar conductance and melting point. The results showed that when the ligand hpmaH_4 coordinated with Cu (Ⅱ) and Co (Ⅱ), the amides were not deprotonated and deprotonated respectively. The ligand qmaH_2 and metal ions generated aromatic complexes. Since the d electrons of the metal participate in the conjugation of the aromatic ring π electrons, the blue shift and fluorescence properties of the aromatic ultraviolet absorption peak are shown, especially the Zn (Ⅱ) complex is the best. When the ligand qmaH_2 is coordinated with Co (Ⅱ) Oxygen absorption properties, generating μ-peroxy bond complex.
