Dipyrrin-based self-assembled architectures

Dipyrrins are bis-pyrrolic derivatives that can be rather easily synthesized and functionalized, forming monoanionic chelates under mild basic conditions. These features make them interesting ligands for the elaboration of discrete and infinite metal-organic architectures. In particular, our efforts have centered on the preparation of polynuclear helicates and Metal-Organic Frameworks using hydrogen or coordination bonding as well as Ag-π interactions. The construction strategies, the structural characteristics and the physical properties of these self-assembled systems will be presented.
