This work deals with the synthesis and the study of multichromophoric systems, based on Bodipy which is known for its oustanding emission properties (high - and values, ) and for both, its donating and withdrawing electronic characteristics. Our goal is to couple the fluorophore to other(s) chromophore(s) sensitive to a specific stimulus, to modulate the Bodipy’s emission. The first part, a bibliographic report, focuses on the various ways to functionalize the Bodipy core and discusses their influence on its spectroscopic properties. The second section aims at describing, first, the emission shift by extension of the core conjugation via a new Knœvenagel type reaction. DFT calculations will support experimental facts. It also focuses on external modulation factors such as disaggregation of Bodipy in aqueous media and anion chelation. The third chapter is fully devoted to the possibility of controlling the fluorescence properties by modification of the counter-chromophore “redox” state (so called electrofluorochromism). To that, two chromophores are used: the s-tetrazine and the ferrocene. Final section gathers the preliminary results of coupling reaction of photochromic species with Bodipy, in order to photocommutate its photophysics properties. Synthetic issues are largely discussed so as to highlight some general synthetic pathways that one needs to follow to succeed.
