emission spectra exhibited obvious solvent effect. With the increase of polarity of solvents the fluorescence spectra changed obviously and appeared blue shift about 60 nm at room temperature. In addition, the light-emitting can be quenched by both electron donor (N,N-dimethylaniline) and electron acceptor (Fullerene), where the processes followed the Stern-Volmer equation. However, when adding 1,4-dicyanobenzene
合成了具有8-羟基喹啉铝和9,9-二苯基芴的新型发光金属配合物(MQPF)3Al2。通过紫外可见吸收和荧光发射光谱研究了光学性质。结果表明,(MQPF)3Al2在THF中的发光量子产率为0.612,并且根据开始吸收估计其发射带隙为3.18 eV的红光。发射光谱显示出明显的溶剂效应。随着溶剂极性的增加,荧光光谱发生明显变化,室温下出现约60 nm的蓝移。另外,可以通过电子给体(N,N-二甲基苯胺)和电子受体(富勒烯)淬灭发光,其中过程遵循Stern-Volmer方程。但是,添加1时
