合成了双极四齿配体双磺基Salophen( BSS)和双极二齿配体双邻菲罗啉( BPA) 。将BSS与镍离子反应,制备了双核镍配合物( Ni-BSS-Ni) 。再将此双核镍配合物与BPA反应,制备了镍配位超分子聚合物溶液。研究了该双核镍配合物的红外光谱、紫外可见吸收光谱和荧光光谱性质。发现BSS与镍形成双核配合物后荧光显著增强,一定条件下,荧光强度与双核配合物的浓度存在定量关系。同时研究了形成的超分子聚合物的共振光散射性质。发现超分子聚合物的形成能使体系产生显著的共振光散射信号,一定条件下共振光散射强度也与超分子聚合物的浓度存在定量关系。结果表明,BSS可作为镍离子的荧光探针。利用镍与BSS和BPG形...

Bis-sulfosalophen ( BSS) which is a ditopic tetradentate ligand and bis-phenanthroline ( BPA) which is a ditopic bidentate ligand were synthesized. Then a binuclear Ni ( II) complex Ni-BSS-Ni with BSS as ligand and its supramolecular polymer ( SP) with BPA as connecter were prepared. The spectral properties of Ni-BSS-Ni were studied by infrared spectrometry,ultraviolet visible absorption spectroscopy and fluorescence spectroscopy. The fluorescence intensity of Ni-BSS-Ni is stronger than that of BSS,and there is a quantitative relationship between the fluorescence intensity and Ni-BSS-Ni concen...
