摘要
以去离子水为溶剂,合成了以Zn2+及Ni2+为中心,以L1,L2[L1=4-氨基-3,5-二甲基-1,2,4-三唑,L2=4-氨基-1,2,4-三唑]及硫氰酸根为配体的两种配合物,对其进行了元素分析、金属离子络合滴定、摩尔电导测定,确定了配合物组成分别为Zn3(NCS)6(L1)6(NO3)2及Ni3(NCS)6(L2)6(NO3)2,同时对两种配合物做了红外光谱、紫外光谱及荧光光谱的测试表征。荧光光谱的测试表明两种配合物均在415nm有一强的荧光发射峰,且镍配合物的荧光要明显强于锌配合物,两种配合物有望成为蓝光发光材料。
The complexes of Zn^2+ , Ni^2+ with 4-amino-3,5-dimethyl-1,2,4-triazole and 4-amino-i, 2,4-triazote were synthesized in water, respectively. By elemental analysis, coordination titration and molar conductivities studies, the compositions of the complexes were suggested as Zna (NCS)6 (L1)6 (NO3)2 and Ni3 (NCS)6 (L2)6 (NO3)2 respectively. The ligands and coordination compounds were studied by means of IR spectra, UV and fluorescence excitation and emission spectra. The IR spectra studies indicate that triazolate was bonded with RE ( Ⅱ ) through nitrogen atoms in the heterocyclic ring. The fluorescence spectra showed that the fluorescence emission intensity of Ni3 (NCS) 6 (L2) 6 (NO3) 2 was stronger than that of Zn3 (NCS) 6 ( L1 ) 6 (NO3) 2.
