(a) Circular dichroism spectra of Fb PPCs recorded at 190–260 nm (50 μM in ACN). (b) Changes in CD spectra upon porphyrin conjugation: Prominent red shift was observed in all Fb PPCs (except Fb( i + 3)) relative to their control peptoids, Pep( i + n ). Spectra of ( i + 2), ( i + 3), and ( i + 6), which were reported previously, are shown for comparison31. (c) Temperature-dependent CD spectra of Fb( i + 2) and Fb( i + 3).
