Self-Organizing Nano-Architectures

I. Grids, sticks, helicates

 

Much interest has been shown for grid-like self-assembled architectures, as well as for helical complexes. We use hydrazone-based ligands to generate and study such metallo-supramolecular architectures. A particular attention is paid to the dynamic aspects of these systems, including reversible interconversions between the complexes. We recently reported a study on magnetic properties of Cu(II) grids and sticks (N. Parizel, J. Ramirez, C. Burg, S. Choua, M. Bernard, S. Gambarelli, V. Maurel, L. Brelot, J.-M. Lehn, P. Turek, A.-M. Stadler, Chem. Commun., 2011, 47, 10951-10953), as well as an interconversion between a grid and a double helicate (A.-M. Stadler, C. Burg, J. Ramirez, J.-M. Lehn, Chem. Commun., 2013, 49, 5733-5735).

 

 

 

II. Macrocyclic chemistry

 

Within this field, we are currently working on both synthesis of macrocycles, and interaction between macrocycles provided with donor atoms and various metal ions. We are investigating shape-defined triangular macrocycles (resulting from the condensation of three molecules of dialdehyde with three molecules of dihydrazine) that can be partially inverted on reaction with metal ions, when they generate trinuclear triangular complexes (A.-M. Stadler, J.-J. Jiang, H.-P. Wang, C. Bailly, Chem. Commun., 2013, 49, 3784-3786).
