processes. Therefore, a series of neutral multinuclear PtII complexes were synthesized and characterized, and their photophysical properties at different concentration were studied. Going from the monomer to dimers, the growth of a new emission band and the enhancement of the emission properties were observed. Upon increasing the platinum units up to three, the monomeric blue emission could not be
铂配合物的自组装是一个有据可查的过程,会导致光物理和电化学行为发生有趣的变化,并导致配合物的反应性发生变化。然而,仍然不清楚多少金属单元必须相互作用才能实现大型组件的所需性能。这项工作旨在阐明相互作用的Pt II单元数量的作用,从而导致光谱性质的增强以及如何解决分子间和分子内过程。因此,一系列中性的多核Pt II合成和表征了配合物,并研究了它们在不同浓度下的光物理性质。从单体到二聚体,观察到新的发射带的增长和发射性质的增强。当铂单元增加至三个时,不再检测到单体蓝色发射,并且观察到由于分子内亲金属相互作用的建立,浓度独立的亮黄色/橙色发射。
