Abstract

In the past decade, there have been significant advancements in the investigation of coherence-related phenomena in organic systems such as biological photosynthetic reaction centers. The d8 Pt(II) dinuclear complex or molecular aggregate with a metal–metal-to-ligand charge transfer (MMLCT) or metal-centered (MC) excited state was reported to show the vibrational coherence phenomenon in the intersystem crossing (ISC) process, due to the Metal–metal (M-M) interaction at excited state. In this study, we review the coherence effect in the Pt(II)-Pt(II) complexes which are speculated to be a coherent energy conversion system. The impacts of coherence on the photo-physics of Pt(II) dinuclear complexes have been discussed and reviewed, including the intersystem crossing process and vibrational wavepacket dynamics.

铂(II)配合物中金属-金属键激发态的振动相干性

在过去十年中，对生物光合反应中心等有机系统中相干现象的研究取得了重大进展。据报道，具有金属-金属-配体电荷转移（MMLCT）或金属中心（MC）激发态的 d8 Pt（II）双核配合物或分子集合体在激发态的金属-金属（M-M）相互作用下，在体系间交叉（ISC）过程中显示出振动相干现象。在本研究中，我们回顾了铂(II)-铂(II)复合物中的相干效应，并推测这是一个相干的能量转换系统。我们讨论并综述了相干效应对铂（II）双核配合物光物理学的影响，包括系统间交叉过程和振动波包动力学。
