Fluorescent organometallic complexes : when the photovoltaic leads to theranostics

subject

description

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 opportunities, theproject has gradually turned towards the application of this type of object « organometallic complex- fluorophore » to the medical field and more particularly the theranostic.The second part of this manuscript describes the application of this type of compounds to thetheranostic field and more specifically the optical theranostic. It begins with a detailed introductionthat defines the challenges of this emerging topic both from the point of view of the imaging astherapy. In the second chapter, we presented the synthesis of theranostic agents including a metalfragment with therapeutic activity linked to a BODIPY, a fluorescent probe known for itsinteresting optical properties. Their characterization and study of their biological properties are alsodescribed. The third chapter focuses on the synthesis of heterobimetallic complexes incorporatingmetals of interest in oncology. These complexes are also being developed for research theranosticagents. The ligand used for medical imaging is the porphyrin. This part also includes thephotophysical studies of our complexes.
