Porphyrin‐based supramolecular nanostructures have been produced by the self‐assembly of porphyrin macrorings with three benzoic acid groups (Acid‐R) on each side of the rings through cooperative carboxyl–carboxyl hydrogen bonds. Structures of the organized Acid‐R were analyzed by AFM, and two clear distribution peaks were observed at 3 and 27 nm in the height‐distribution histogram. From the overall...
Binding constants and thermodynamic parameters for 1:1 complexation of a porphyrin macroring, self-assembled from three trisporphyrinatozinc through imidazole–Zn coordination on the terminal porphyrins, with several multidentate pyridyl and fullerenyl ligands were examined. In benzonitrile, the ligand having one fullerenyl and two coordinative pyridyl moieties surprisingly afforded the highest affinity...
