吡啶-三唑Os(II)配合物的光谱性质和取代基效应的理论研究
为了探究吡啶-三唑Os(Ⅱ)配合物的光谱性质及取代基效应对其配合物发光性质的影响, 采用密度泛函理论DFT中的B3LYP方法优化了系列吡啶-三唑Os(Ⅱ)配合物[Os(ptz)2L2](L=PH3; ptzH=(2-吡啶)-1, 2, 4-三唑( 1 ); [Os(bptz)2L2] (bptzH=3-叔丁基-5-(2-吡啶)-1, 2, 4-三唑 ( 2 ); [Os(fptz)2L2] (fptzH=3-(三氟甲基)-5-(2-吡啶)-1, 2, 4-三唑 ( 3 ); [Os(fbtz)2L2] fbtzH=3-(三氟甲基)-5-(4-叔丁基-2-吡啶)-1, 2, 4-三唑) ( 4 ) 的基态和激发态几何结构. 通过TD-DFT方法结合PCM溶剂化模型计算了配合物分子 1~4 在二氯甲烷溶液中的吸收和发射光谱, 指认了它们的跃迁性质. 通过分析比较计算结果, 论述了取代基效应对配合物 1~4 的磷光发射及磷光量子产率的影响.
