challenging to investigate the dynamics of coordination-driven self-assembly due to the existence of multiple intermediates and many possible processes. By taking advantage of the high sensitivity and efficiency of fluorescence-resonance energy transfer (FRET), FRET was successfully employed to real-time monitor the dynamic behavior of coordination-driven self-assembly. The Förster energy transfer
fluorescent 3-hydroxy-4-pyridinone (3,4-HPO) ironchelator functionalized with a carboxyrosamine fluorophore (MRB20). The antibacterial activity of MRB20 was assessed against representative strains from clinically relevant Gram-positive and Gram-negative bacterial species and further compared with the inhibitory effect of a set of structurally related ironchelators including Deferiprone (1,2-dimethyl-3-

rosamine platforms through an amide linkage and were synthesized by using microwave‐assisted coupling reactions of carboxyl‐ or amine‐substituted rosamines with the corresponding catechol units and subsequent deprotection. RosCat1 possesses a reverse amide, whereas RosCat2 has the usual oriented amide bond (HNCO vs. CONH, respectively). The ligands were characterized by means of NMR spectroscopy, mass‐spectrometry
