The creation of nano/microstructures based on molecular components possessing defined functionalities is a very fascinating field at the cross point of different disciplines.Our effort, in this talk, focuses on the assembly of functional molecules to form crystalline or soft materials. The molecules employed for the assemblies are metal complexes based on Pt(II) or Ir(III) metal ions coordinated to ligands able to induce strong secondary interactions. All the complexes show emission properties that can be modulated upon the formation of the aggregates, or by the interaction of the materials with other systems. The assembly can therefore be used to probe the environment or can result in a new material with very exciting properties. The degree of interaction between the different units can be tuned using different ligands as well as different media where the complexes are solubilized or dispersed. The piezochromic behavior of some of these materials will be discussed and rationalize using different packing modes.We have recently reported the aggregation induced emission of a Pt(II) compound bearing a tridentate, dianionic ligand and also showed, that appropriate ancillary ligands can be useful to gelate solvents of different polarity, such as dichloromethane and DMF.
