Supramolecular Structure of Extrinsically Chiral Porphyrin Hetero-Assemblies and Achiral Analogues.
Publication date: 2007
Journal: Advanced Materials
Abstract: Supramolecular structures of porphyrin hetero-assemblies and the achiral analogous are determined through energy dispersive X-ray diffraction. In presence of phenylalanine, CuT4 cationic and H2TTPS anionic porphyrins yield a suprachiral a-helix persisting even after removing the chiral template. The analogous synthesis performed without the template-imprinting agent provides an amorphous arrangement, hence an achiral structure.
Template and target information: phenylalanine, CuT4 cationic porphyrin, H2TTPS anionic porphyrin
