A novel assembly of cyclodextrins with 4,4′4″,4‴-(21H,23H-porphine-5,10,15,20-tetrayl)tetrakis(benzoic acid) through hydrogen bonds
Abstract
Semi-closed assemblies are formed from cyclodextrins (CyDs) and 4,4′,4″,4‴-(21H,23H-porphine-5,10,15,20-tetrayl)tetrakis benzoic acid (PTTKBA); the assemblies are a new group of host molecules that possess inclusion properties different from those of the component CyDs.
