环金属钌配合物具有良好的氧化还原和光物理性质,在诸多光电领域如染料敏化太阳能电池、电致变色、电子转移等方面具有重要应用.环金属钌配合物的合成方法主要包括“后期金属化”、“前期金属化”、“转金属化”三种方法.环金属配合物具有丰富的结构多样性.环金属配合物由环金属配体和辅基配体与金属螯合形成.环金属配体包括N^C、N^N^C、N^C^N和C^C^C-类型多齿配体.辅基配体主要包括吡啶、咪唑、三唑、嘧啶等杂环.碳-金属键的引入大大降低了钌配合物的氧化还原电位.通过改变环金属配体和辅基配体的结构,可以对金属的氧化还原电位进行有效调控.金属钌配合物的氧化还原电位对敏化电池的性能以及电子转移的过程具有重要的影响.
Cyclic metal ruthenium complexes have good redox and photophysical properties and have important applications in many optoelectronic fields such as dye-sensitized solar cells, electrochromism, electron transfer, etc. The synthesis methods of the ruthenium complex include: Metallization, Metallization, Metallization, etc. Cyclic metal complexes are rich in structural diversity. Cyclic metal complexes consist of a combination of a cycloaliphatic ligand and a prosthetic ligand with Metal chelate formation.Retalline ligands include N ^ C, N ^ N ^ C, N ^ C ^ N and C ^ C ^ C- type polydentate ligands.The auxiliary ligands mainly include pyridine, imidazole, triazole , Pyrimidine etc. The introduction of carbon-metal bond greatly reduces the redox potential of the ruthenium complex.The redox potential of the metal can be effectively regulated by changing the structure of the ring metal ligand and the cofactor ligand Metal ruthenium The redox potential of the complex has an important effect on the performance of the sensitized battery and the electron transfer process.
