Fluorescent organometallic complexes : when the photovoltaic leads to theranostics
2013
The goal of my PhD thesis was to synthesize new molecules, which give access to fluorescentorganometallic complexes with interesting properties for photovoltaic and theranostic. In thisproject, several main points have been studied.The first part of this manuscript concerns the synthesis of new metallocene and metalloporphyrinsbasedorganometallic complexes to the design of solar cells. After a short introduction, wepresented the synthesis of titanium complexes and metalloporphyrins in the first chapter. Inparticular, we described the synthesis of model compounds and the difficulties encountered duringthe transition to porphyrin derivatives. However, in view of results obtained and opportuni…
Synthesis, Electrochemistry, and Photophysics of Aza-BODIPY Porphyrin Dyes
2016
International audience; The synthesis of dyad and triad aza-BODIPY-porphyrin systems in two steps starting from an aryl-substituted aza-BODIPY chromophore is described. The properties of the resulting aza-BODIPY-porphyrin conjugates have been extensively investigated by means of electrochemistry, spectroelectrochemistry, and absorption/emission spectroscopy. Fluorescence measurements have revealed a dramatic loss of luminescence intensity, mainly due to competitive energy transfer and photoinduced electron transfer involving charge separation followed by recombination.
