We created holes in single-wall carbon nanohorns (SWCNH) by oxidation (SWCNHox) and investigated how the hole size affected the incorporation of C 60 in SWCNHox and their release from it. The incorporation of C 60 inside SWCNHox first occurred when the holes were opened by oxidation at 475°C. It was followed by a steep increase in the incorporation quantity with increasing oxidation...
A combination of π–π stacking and electrostatic interactions was used to integrate an anionic porphyrin (H 2 P 2− ) with carbon nanohorns (CNHs), mediated by positively charged pyrene (pyr + ) units. The resulting water-soluble CNHs–pyr + –H 2 P 2− nanoensemble was characterized by optical spectroscopy and electron microscopy techniques. The strong fluorescence...
