The cluster formation, electrophoretically deposited film structures, microwave conductivity, and photoelectrochemical properties of the composites consisting of single-walled carbon nanotube (SWNT) with C60, C70, or C84 have been systematically compared for the first time. In an ortho-dichlorobenzene (ODCB)−acetonitrile mixture, the higher fullerenes (i.e., C70 and C84) were found to form single composite clusters exclusively with highly soluble SWNT bearing bulky swallow-tailed substituents (f-SWNT). These are in marked contrast with the unselective formation of three different clusters in the C60−f-SWNT composites. Electrophoretic deposition of the composite clusters yielded the corresponding films on nanostructured SnO2 electrodes. The microwave conductivity measurements revealed the occurrence of electron transfer from C70 to f-SWNT, followed by electron transportation through f-SWNT, in addition to electron hopping through C70 molecule arrays due to the alignment of C70 on the sidewalls of f-SWNT in...
