Current Research Interests (see also SOF group website)

• Elaboration of NEW BUILDING BLOCKS BASED ON PORPHYRINS AND FLUORENE UNITS. Fascinating super- of supra- molecular assemblies can be obtained with remarkable photonic properties from such building blocks. Due to efficient energy transfer between the fluorenyl arms, which act as antennas, and the porphyrin cores, which act as emitters, these LINEAR OR DENDRIMERIC assemblies behave as red emitters after selective UV or visible excitation.
• A second of my current concerns is related to the use of related PLATINUM PORPHYRINS COMPLEXES which can be used as red phosphors in OLEDs. Several such solid-state devices have now been prepared and their electroluminescence performance was assessed.

Ongoing collaborations

• J.A.G. Williams, M. A. Fox (Durham University - UK): Fluorescence measurements
• M.G. Humphrey, M. P. Cifuentes, Australian National University (ANU - Canberra/Australia): Synthesis of organometallic redox-switchable molecular assemblies for cubic NLO.
• M. Blanchard-Desce at the ISM (UMR 5255, univ. Bordeaux 1): Two-photon absorption measurements.
• I. Ledoux at the LPQM (ENS Cachan/France): THG, EFISH or HRS measurements.
• V. Fattori (University Bologne - Italy): Luminescent molecules for OLEDs elaboration
