density functional theory were carried out on these complexes. Our benchmark revealed that the M06-L method has results close to those of the experiment. Furthermore, to gain a deeper insight into electronic transitions, several excitation processes were investigated at the TD-DFT-SMD-MN12-L/gen level. The results showed that in the designed complexes, the dominant transition is between the 4dZ2 electron
近红外发光材料最近受到大量应用的广泛关注,包括固态照明、生物成像剂、光伏电池和电信行业。通过在基于苯硫酚-菲咯啉的辅助配体上添加不同的给电子或取电子基团,我们合成并光电表征了一系列新型离子型钌配合物,即 RuS、RuSCl、RuSMe 和 RuSNH 2,用于发光电化学电池。合成的复合物是溶液中 584-605 nm 范围内的强红色发射体,这取决于辅助配体上电子供体/受体部分的取代。为了找到合适的量子力学方法,对这些配合物进行了基于时间相关密度泛函理论的基准计算。我们的基准显示 M06-L 方法的结果与实验结果接近。此外,为了更深入地了解电子跃迁,在 TD-DFT-SMD-MN12-L/gen 水平上研究了几个激发过程。结果表明,在设计的配合物中,占主导地位的转变是在 4d Z 2Ru(粒子)的电子和辅助配体(空穴)的 π* 轨道。在不添加任何电子或空穴传输层的情况下,通过简单的沉积方法制造了包括这些复合物和
