合成了3个钌髤配合物,[Ru(bpy)2(SB)](PF6)2、[Ru(bpy)(SB)2](PF6)2和[Ru(SB)3](PF6)2(bpy=2,2′-bipyridine,SB=4,5-diaza-9,9′-spirobifluorene),通过核磁和元素分析对配合物的结构进行了确定。[Ru(bpy)2(SB)](PF6)2通过X射线单晶衍射确认了结构。研究了配合物的光物理性能。结果表明[Ru(bpy)2(SB)](PF6)2在乙腈中的发桔红光,波长为606 nm,量子产率约为0.001 2。在同样条件下[Ru(bpy)(SB)2](PF6)2和[Ru(SB)3](PF6)2的发光非常微弱甚至几乎没有发光。还研究了这些配合物的电致化学发光性能。随着配体中SB含量的增加,发光的峰电压从1.36 V增加到1.58 V,相对发光强度从731降低到52。
Three Ru ruthenium complexes, [Ru (bpy) 2 (SB)] (PF6) 2, [Ru (bpy) (SB) 2] (PF6) 2 and [Ru (SB) 3] (PF6) 2 (bpy = 2,2’-bipyridine, SB = 4,5-diaza-9,9’-spirobifluorene), the structure of the complex was confirmed by NMR and elemental analysis. [Ru (bpy) 2 (SB)] (PF6) 2 confirmed the structure by X-ray single crystal diffraction. The photophysical properties of the complexes were studied. The results showed that [Ru (bpy) 2 (SB)] (PF6) 2 was orange-red in acetonitrile with a wavelength of 606 nm and a quantum yield of about 0.001 2. Under the same conditions, the luminescence of [Ru (bpy) (SB) 2] (PF6) 2 and [Ru (SB) 3] (PF6) 2 is very weak even with little luminescence. The electrochemiluminescent properties of these complexes were also studied. With the increase of SB content in the ligand, the peak voltage of luminescence increased from 1.36 V to 1.58 V, and the relative luminescence intensity decreased from 731 to 52.
