Photophysics of transition metal complexes

Due to their rich luminescence, transition metal complexes find applications in multiple fields, spanning from photochemistry and photocatalysis (see Chapter 4) to molecular electronics, OLEDs, intracellular sensors and bioimaging reagents. However, the practical application of novel luminescent complexes cannot ignore a profound knowledge of the fundamentals of their photophysical properties. In 2015–2016, much research has been actually addressed to this issue and this chapter will attempt to summarize the major advances in the scope of the photophysics of d-block metal complexes.
