Dipyrrolydiketones BF complex was synthesized and characterized by NMR, HRMS, and single crystal diffraction. In non-polar environment, this BF containing dye emitted bright blue-green fluorescence. No significant spectra shift was observed both in absorption and emission spectra, which indicates the insensitivity of absorption/emission toward environment. The alkyl substituted pyrrole rings lead to its highly emission character in solid state by enhancing the distance between dye molecules. Absolute quantum yields were determined to be 0.51-0.78/0.36 in selected organic medium and solid state, respectively. The emission dynamics was investigated by fluorescence lifetime and both monoexponential and bi-exponential decay was observed.
二吡咯二酮 BF 配合物通过 NMR、高分辨质谱和单晶衍射进行了合成和表征。在非极性环境中，这种含 BF 的染料发出明亮的蓝绿色荧光。在吸收和发射光谱中均未观察到明显的光谱位移，这表明该染料对环境的吸收/发射不敏感。烷基取代的吡咯环通过增加染料分子之间的距离，使其在固态下具有高度的发光特性。在选定的有机介质和固态中，绝对量子产率分别确定为 0.51-0.78/0.36。通过荧光寿命研究了发射动力学，观察到单指数和双指数衰减。
