3. Illustrative Applications

The LCMD group members also work on collaborative projects with our experimental colleagues. Those collaborations make use of the formalisms developed in LCMD. Check how does dDsC perform on real-world applications involving pi-conjugated assemblies, chemosensors and weakly-bound dimers of metallocenes:

Four-electron oxygen reduction by an assembly of Tetrathiafulvalene 

In collaboration with LEPA (JACS2011), we have identified assemblies of tetrathiafulvalene that are expected to be involved in the 4 electron reduction of oxygen into water.

Fluorescence sensing of caffeine in water with polysulfonated pyrenes

In collaboration with LCS we have identify a highly selective and sensitive fluorescent caffeine sensor using the LOL design criterion (ChemComm2011) (OrgBioMol) and (ChemComm2012).

On this basis, the group of Prof. Kay Severin devised a stick to find out if your coffee is really decaffeinated:

 

Biphasic water splitting by Osmocene

Detailed electrochemical, spectroscopic and computational studies indicate that osmocene can liberate an electron to produce H2 from protons. The oxidized osmocene forms a weakly bound dimer that reacts to split water forming an osmium hydride and an osmium hydroxide. Photolysis of the Os(iv) hydroxide species leads to an osmium peroxy species that further reacts to liberate O2. The study of LEPA and LCMD suggests novel catalytic mechanisms relying on bimetallic dimers for the photocatalytic splitting of water. Check PNAS, 2012, 29, 11558.
