Electrochemistry, supramolecular chemistry, functionalized dendrimers
Our group's research interests focus on the general area of Supramolecular Electrochemistry. For more than twenty years we have been investigating the electrochemical properties of a number of supramolecular systems, from host-guest complexes to self-assembled monolayers and dendrimers. In particular, we have been especially interested in the idea of using redox conversions to control the structure of supramolecular assemblies. This possibility is very relevant to the design of molecular devices. We are also interested on the effects that supramolecular structure may exert on the kinetics and thermodynamics of electron transfer reactions. Illustrative examples of specific systems in which we are currently exploring these general ideas are:
- Cucurbit[n]uril Complexes: We are particularly interested in the development of analytical applications based on the controlled formation of highly fluorescent J-aggregates.
- Molecular Capsules: Our efforts in this area are geared to understand electron transfer processes involving species trapped inside molecular capsules of variable sizes.
- Functionalized Dendrimers: We still continue our long-standing research effort on the properties of redox active and fluorescent dendrimers. We are also working on dendrimer functionalization to facilitate effective DNA delivery to cells.
