Dynamic control of dendrimerfullerene association by axial coordination to the coreElectronic supplementary information (ESI) available: Experimental section, synthesis, titrations, and thermodynamic parameters. See DOI: 10.1039/c3cc43249a

The effect of axial coordination of pyridine derivatives to the core porphyrin on the fullerene encapsulation of the 4th generation carbazolephenylazomethine dendrimer ( ZnPG2-2 ) was investigated. The axial coordination of large (bulky) pyridine derivatives affects the cavity in an allosteric manner, and the size-selectivity of the fullerene association could be controlled. Fullerene association of the carbazolephenylazomethine dendrimer was controlled by bulky pyridine complexation to the core porphyrin in an allosteric manner.
