Luminescent supramolecular assemblies

Abstract

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.
