摘要
选择1-苯基异喹啉(piq)作为金属化C^N配体,带有噻吩取代基的2,2’-联吡啶作为N^N配体,设计并合成了铱配合物[Ir(piq)2(tbpy)](PF6)。对所得到的配合物进行了结构表征,并详细研究了这种配合物的光物理和电化学性质,讨论了结构和性能的关系。结果表明,在联吡啶上引入噻吩取代基,对配合物的电化学和光物理性质影响较小;使配合物的还原电势和Eg稍有降低;噻吩取代基的引入使配合物发射光谱略有红移。
A novel charged diiminoiridium [ Ir (piq) 2 (tbpy) ] ( PF6 ) complex containing C^N ligands of 1 -phenylisoqinoline and N^N ligand of 5-(thiophen-2-yl)-2' 2-bipyridine has been prepared and fully characterized. Photophysical and photoelectric properties of this complex were investigated, and the relationship between structure and properties was discussed, and photophysical properties of this complex, led to the reduction potential and energy gap of the complex reduce and led to emission spectra of the complex red shift a little.
