Figure 2

a: 1D 19F NMR spectra of the (F6)(Na+)E(A-A)(BZI) complex (black), the (F6)(Na+)E(Q)indoline complex (red) and the (F6)(Na+) E(Q)aniline complex (green). Conditions: αβ, 605 μM; Na+, 100 mM; L-Ser, 200 mM; and when present, BZI, 10 mM; indoline, 5 mM; aniline, 10 mM. b: UV/Vis absorption spectra of the (F6)(Na+)E(A-A)(BZI) complex (black; αβ, 7.5 μM) and of the (F6)(Na+)E(Q)indoline (red; αβ, 1.36 μM) from the NMR samples in Figure 2a.
