This study shows that incorporation of [Rub2m-OH]2+ at the N-terminus of the Fs peptide enhances its stability by ∼0.15 kcal/mol through the mechanism of dipole−dipole coupling at the excited state, suggesting that photoinduced charge generation at a well-controlled and specific location provides a convenient means to trigger helix-coil transition on nanosecond or even faster time scales.
