CD Investigation of Porphyrin–Porphyrin Interaction with Links to Acyclic β-Sheet Peptide Self-Assembled in an Aqueous Media

Abstract Amphiphilic peptide, Ac-Cys(Por)-Lys-Val-(-Ser-Val-)n-Lys-Val-NH2 (n = 0 or 1, Cys(Por) = side-chain porphyrin-linked Cys), self-assembled to form the β-sheet in buffer solution-2,2,2-trifluoroethanol and showed exciton coupled Cotton effects in the porphyrin region due to the closely oriented porphyrins.
