This phenomenon, termed clusteroluminescence, arises from the spatial confinement of electron-rich functional groups, leading to electronic delocalization and the formation of emissive clusters. Understanding this mechanism can open new possibilities for non-aromatic fluorescent peptides as bioimaging tools. This project focuses on single alpha-helical peptides (SAHs), particularly the E-R/K alpha-helical motif, which consists of repeating anionic (Glu) and cationic (Lys/Arg) residues that stabilize the structure through salt bridges.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/peptidesnon-aromaticfluorescencebioorthogonalcatalysis230224 Péptidos230106 Fluorimetríadoctoral thesisopen access
