Photophysics of transition metal complexes (2017-2018)

This Chapter aims at summarizing the major advances achieved, over 2017 and 2018, in the scope of the photophysics of d-block metals complexes. In the last years, one of the central research themes has been the development of luminescent complexes based on earth-abundant metal ions, which could effectively replace second and third-row transition-metal compounds in e.g. light-emitting diodes, dye-sensitized solar cells, photocatalysis and sensing. However, although inconvenient in some ways, second and third-row transition-metal chromophores have continued to be important building blocks in the development of biomedical drugs and optical sensors, as well as in artificial photosynthesis and photocatalysis.
