A peptide-based electron-transfer system has been designed in which the specific positions of redox-active metal complexes appended to either an alpha-helix, or an alpha-helical coiled-coil, can be reversed to test the effect of the helix dipole in controlling photoinduced electron-transfer rates. Two 30-residue apopeptides were prepared having the following sequences: (I) Ac-K-(IEALEGK)(ICALEG...
Fluorescence microscopy has undergone a dramatic evolution over the past two decades with development of super-resolution far-field microscopy methods that break the light diffraction limited resolution of conventional microscopy, offering unprecedented opportunity to interrogate cellular processes at the nanoscale. However, these methods make special demands of the luminescent agents used for ...
Multinuclear ruthenium polypyridyl complexes are currently the subject of extensive investigations, their photophysical properties making them ideal components for photochemically and electrochemically driven molecular devices.1 Among these compounds, mononuclear ruthenium complexes containing biimidazole or bibenzimidazole (bibzimH2) type ligands2 have been shown to be excellent building block...
