Long-range electron transfer in artificial systems with d6 and d8 metal photosensitizers

This review article summarizes the research progress made since the year 2000 in the field of long-range electron transfer with synthetic systems that use d6 or d8 metal complexes as photosensitizers. This includes charge transfer over distances greater than 10 Å in both covalent and noncovalent donor–bridge–acceptor systems. Metal complexes of Ru(II), Os(II), Re(I), Ir(III), Ir(I), and Pt(II) are considered.
