【摘要】 合成了两种金属配合物{[Cu2(pztc)(4,4′-bpy)(H2O)4]·6H2O}n(1),{(H2bpe)[Cd(pztc)(H2O)2]·2.5H2O}n(2)(H4pztc=吡嗪-2,3,5,6-四甲酸,bpy=4,4′-联吡啶,bpe=1,2-二(4-吡啶基)乙烯),测定了其晶体结构,并对其进行了红外光谱、荧光光谱和热重分析等表征。两种配合物均为二维层状结构,但其中吡嗪四酸的配位方式不同。配合物2具有蓝色的荧光,最大荧光发射峰在475 nm。测试了配合物1的电子顺磁共振谱,结果显示Cu2+的特征谱带。更多还原

【Abstract】 Two complexes with pyrazine polycarboxylic acid, namely {[Cu2(pztc)(4,4′-bpy)(H2O)4]·6H2O}n(1),{(H2bpe)[Cd(pztc)(H2O)2]·2.5H2O}n(2),(H4pztc=pyrazine-2,3,5,6-tetracarboxylic acid, bpe=1,2-bis(4-pyridyl)ethane,4,4′-bpy =4,4′-bipyridine), have been prepared by modifying the reaction conditions at room temperature and characterized by IR, elemental analysis, thermal gravimetric analysis, fluorescence measurement and single crystal X-ray diffraction analysis. The structures of two complexes are two-dimensional(2D) networks, but H4 pztc has different connection modes in 1 and 2. Complex 2 shows good luminescence properties in solid state at room temperature. Electron Paramagnetic Resonance(EPR) spectra of complex 1 is studied. CCDC: 1039147, 1;1039296, 2.更多还原
