Abstract

Porphyrin-peptide hexadecamer molecules form supramolecular nanohybrids preferentially with semiconducting carbon nanotubes (SWCNTs) by wrapping of peptidic backbone in P(H2P) 16 and π-π interaction between porphyrins and nanotubes. Such supramolecular nanohybrid formation results in de-bundling of nanotubes and extraction of semiconducting SWCNTs from starting purified SWCNTs as indicated by the high-resolution transmission electron microscopy (HRTEM) image and the Raman spectrum of SWCNTs wrapped with P(H 2P) 16, respectively. The photoexcitation of the supramolecular nanohybrids affords the long-lived charge-separated state via photoinduced electron transfer from P(H2P) 16 to SWCNTs.
