Due to the quenching behavior of open-shell d-metals there remains a lack of fluorescent turn-on sensors for Fe(III). Recent efforts in our laboratory have afforded us a novel class of BODIPY derived catechols that display fluorescence enhancements in the presence of Fe(III). The luminescent response of this class of compounds is modulated by a photoinduced electron transfer (PeT) mechanism between the catechol moiety and the BODIPY chromophore (Figure 1). Moreover, the turn-on behavior of this system is not restricted to organic solvents as large fluorescence enhancements were observed in aqueous media buffered at pH=7. This presentation will entail a discussion of the synthetic methodology employed and the spectroscopic properties of this remarkable class of compounds.
