Controlled Self-assembly of Oligopeptides Bearing Electron Donor and Acceptor Units on the Side Chains to Form beta-Sheets with Selective pi-Stacking Configuration
We describe the formation of beta-sheets from heptapeptides bearing one electron-donating free-base porphyrin and two electron-accepting naphthalenediimides on the side chains. The porphyrin units in the resultant beta-sheet fibers form J- or H-type aggregates, depending on the protonated state of the porphyrin unit in the assembling process.
