　　Summary:
　　Amides with the synthesis of simple structure with variable and adjustable base features such as bit at the end of the rare earth ions have a better ability to identify the coordination, the paper ends by changing the ligand-based design and synthesis of functional Neodymium Magnets groups out of the 13 new of benzoic amide derivatives as well as 10 kinds of novel structure and good fluorescence properties of rare earth organic complexes. The study is divided into the following four parts:
　　(1) benzamide as the basic skeleton, six new synthetic ester containing benzamide derivatives [N-benzyl-2 - (substituted acyloxy) benzamide], by 1H NMR, mass spectrometry, elemental analysis and infrared spectra analysis by means of target compounds and intermediates for structural characterization.
　　(2) the synthesis of N-benzyl-2 - (substituted acyloxy) benzamide ligand, Eu (Ⅲ) ion as the center, six new synthesis of europium-N-benzyl-2 - (instead of acyl-oxy) benzamide fluorescent complexes. Analysis by titration with EDTA, molar conductance, elemental analysis, IR, UV spectra and thermal analysis methods to determine the target structure and composition of complexes; fluorescence spectroscopy study of the target fluorescence properties of complexes. The results show that: Six compounds containing ester N-benzyl-2 - (substituted acyloxy) benzamide with europium ions to form stable complexes, Eu-N-benzyl-2 - (benzoyl oxy) benzamide, Eu-N-benzyl-2 - (benzoyl-methyl-oxy) benzamide, Eu-N-benzyl-2 - (p-chloro-benzoyl-oxy) benzoic amide, Eu-N-benzyl-2 - (p-methoxy benzoyl oxy) benzamide and Eu-N-benzyl-2 - (benzoyl chloride between oxy) benzamide five kinds issued a europium ion complexes characteristic red fluorescence, color is good, the fluorescence intensity; Eu-N-benzyl-2 - (acetoxy benzene) benzamide ligand complexes issued N-benzyl-2 - (benzene acetyloxy) benzamide green fluorescence studies have shown that differences in the structure of the complex leads to complexes of different fluorescent colors.
　　(3) benzamide as the basic skeleton, synthesized seven new sub-containing amino benzamide derivatives [N-benzyl-2 - (aryl Bolkiah amino carbamyl-methoxy) benzamide] by 1H NMR spectroscopy, mass spectrometry, elemental analysis and infrared spectra analysis by means of target compounds and intermediates for structural characterization.
　　(4) to the synthesis of N-benzyl 2 - (aryl Bolkiah amino carbamyl-methoxy) benzamide ligand, Eu (Ⅲ) as the central ion, synthesis of four new europium-N - Benzyl-2 - (aryl Bolkiah amino carbamyl-methoxy) benzamide fluorescent complexes. http://www.everbeenmagnet.com/en/products/110-sintered-neodymium-magnets Seven kinds of compounds containing imino, only N-benzyl 2 - (nitrophenyl imino between carbamyl-methoxy) benzamide, N-benzyl-2 - (p-methoxy-phenyl imino ammonia formyl methoxy) benzamide, N-benzyl-2 - (p-imino-carbamyl-methoxy) benzamide, N-benzyl-2 - (benzylidene-amino carbamyl methoxy yl) benzamide 4 kinds of europium ions with center to form a stable complex, fluorescence spectroscopy results showed that the four kinds of complexes of the ligand fluorescence emitted fluorescence of europium ion perturbation makes the luminous intensity of the ligand increases.
