DESCRIPTION:Self-assembly of chemical entities represents a very attractiv
 e way to create a large variety of ordered functional structures and compl
 ex matter. While much effort has been devoted towards the preparation of s
 upramolecular nanostructures\, based on different chemical building blocks
 \, ultimate understanding of mechanistic insights and monitoring of the as
 sembly events are often elusive\, precluding deep and comprehensive contro
 l on the final structures.\n\nIn this contribution we report on luminescen
 t metal complexes undergoing self-assembly in different types of aggregate
 . We demonstrate how even small changes in molecular design can completely
  inhibit or enhance the formation of organized supramolecular architecture
 s\, leading to a deep understanding of the key factors affecting the whole
  polymerization process.\n\nFor some of the compounds we have been able to
  control the assemblies and obtain uniform size of the aggregate that can 
 even be converted in a thermodynamic unstable species by light.\n\nThe ass
 embly process can also be driven inside small channels such as in porous s
 ilica-based materials resulting in the possibility to obtain stable lumine
 scent clusters or unusual properties of the molecules entrapped.\n\n1. R.N
