    The term “photoredox catalysis” has been expanded since the report (<i>Science</i>, <b>322</b>, 77 (2008)) by Prof. David W. C. MacMillan who won the Novel Prize in Chemistry in 2021. He cited our old work that a chiral ruthenium complex could proceed with photo-induced asymmetric synthesis. The topics on photosensitization by ruthenium tris(bipyridine) complexes are herein described from the viewpoints of photo-induced asymmetric synthesis, syntheses of ruthenium tris(heteroleptic) and the other derivatives containing “Peptide Origami”, photocatalytic CO<sub>2</sub> reduction toward artificial photosynthesis.

  • Recent Trend in the Measurements of Luminescence Spectra and Quantum Yields of Metal Complexes Reviewed

    石田 斉

    Bull. Jpn. Soc. Coord. Chem.   64   14 - 24   2015.3

     More details

    Language:Japanese   Publishing type:Article, review, commentary, editorial, etc. (scientific journal)   Publisher:Japan Society of Coordination Chemistry  

    In a luminescent metal complex, the singlet excited state readily converts the excitation energy to the triplet state by increasing the spin-orbit coupling due to the presence of a heavy atom such a metal ion. The emission is called phosphorescence, which can be frequently observed even at room temperature. This review indicates the problems that inorganic chemists may confront while measuring the emission spectra and the emission quantum yields of metal complexes and introduces the IUPAC project to prepare the guidelines for the measurements. Common textbooks in photochemistry usually aim at the physical and/or organic chemists, and they are not always suitable for inorganic chemists who measure the room-temperature phosphorescence. This review describes the procedures for measuring the emission spectra and the quantum yields of the metal complexes in solution from the viewpoints of selection of solvent, sample concentration, de-aeration, and temperature control. It describes both the relative and absolute methods to determine the emission quantum yields. It further indicates that the measurements of solid-state samples are much more difficult than solutions and recommends that the experimental conditions are reported in as much details as possible.

    Substituent effects of the ruthenium complexes have been investigated on the photocatalytic CO2 reduction. The positions of methyl groups introduced in the bipyridyl ligand of the ruthenium complexes affect the catalytic activities. The effects have been discussed in terms of back electron transfer from the catalyst to the photosensitizer. In this work, the functionalization of the metal complexes by utilizing the peptides containing unnatural bipyridyl amino acid has also been assessed. Specifically, the ruthenium dinuclear complex linked with a peptide has been newly synthesized, and the photocatalytic CO2 reduction is found to show the different product selectivity from that by the mononuclear complex.

    金属錯体はその活性や触媒選択性を分子レベルで制御することができることから、分子触媒として注目を集めている。特に、人工光合成への応用の観点から光化学的CO2還元触媒の開発が活発に研究されているが、同反応の温度依存性を研究した例は少ない。本研究では、ルテニウム錯体触媒を用いた光化学的CO2還元反応を低温条件下で行うことによって反応生成物比の変化を検討するとともに、触媒反応に関する情報を得ることを目的とする。
    我々はこれまでルテニウム錯体を触媒とする光化学的CO2還元反応を、水をプロトン源とすることによって行ってきたが、本研究では低温条件下(-40℃~40℃)で反応を行うためにエタノールをプロトン源として用いた。ルテニウム錯体を触媒とする光還元反応は光増感分子と電子源を共存させる必要があり、光照射により光増感分子が電子源から触媒へと電子を供給する電子リレー系と、電子を受け取った触媒がCO2を還元する触媒反応系から構成されることがわかっている。本研究では、エタノールの比率を増加させることによって触媒反応の律速過程が触媒反応系から電子リレー系へとシフトすることを明らかにした。このことは還元反応生成物比の温度依存性にも影響し、エタノール比が低い場合には温度が高くなるにつれてギ酸生成が増加するのに対し、エタノール比が高い場合には温度が高くなるにつれて一酸化炭素生成が増加することを見出した。これらの結果から、両者の活性化エネルギー差を求めることができ、触媒反応機構に関する知見を深めることができた。
