A bromo tricarbonyl rhenium(I) complex with a thiophene-functionalized bis(pyrazolyl) pyridine ligand (L), ReBr(L)(CO)(3) (1), has been synthesized and characterized by variable temperature and COSY 2-D (1)H NMR spectroscopy, single-crystal X-ray diffraction, and photophysical methods. Complex 1 is highly luminescent in both solution and solid-state, consistent with phosphorescence from an emissive (3)MLCT excited state with an additional contribution from a LC (3)(pi-->pi*) transition. The single-crystal X-ray diffraction structure of the title ligand is also reported.
一种溴三羰基铼（I）配合物，具有噻吩功能化的双（吡唑基）吡啶配体（L），ReBr（L）（CO）（3）（1），已经通过变温和 COSY 2-D（1）H NMR 光谱、单晶 X 射线衍射和光物理方法进行了合成和表征。配合物 1 在溶液和固态中都具有很高的发光性，与来自发射（3）MLCT 激发态的磷光一致，并有来自 LC（3）（pi-->pi*）跃迁的额外贡献。标题配体的单晶 X 射线衍射结构也有报道。
