Luminescent supramolecular assemblies

There has been a continuous interest in the study of transition metal complexes. In particular, the variation in coordination modes and geometries of d⁸ and d¹⁰ metal centers have allowed the formation of supramolecular assemblies with different structures and topologies through the interplay of coordination bonds, non-covalent metal−metal interactions and other intra-/intermolecular interactions, which is in sharp contrast to octahedral d⁶ metal complex systems. Not only are metal complexes of d⁸ and d¹⁰ transition metal centers luminescent, many of their supramolecular assemblies are luminescent in nature due to the availability of different excited states; some of which could be modified by metal–metal interactions. The present chapter will give an overview on the luminescent supramolecular assemblies based on d⁸ metal centers including platinum(II), palladium(II), rhodium(I) and gold(III), and d¹⁰ metal centers including gold(I), silver(I) and copper(I), that were reported after 2013. The discussion will begin with luminescent supramolecular assemblies based on platinum group metals with d⁸ electronic configuration, followed by an overview of the luminescent assemblies based on d¹⁰ coinage metal centers.
