Facile construction of an ultra-thin [60]fullerene layer from [60]fullerene–homooxacalix[3]arene complexes on a gold surface

A hexacationic homooxacalix[3]arene–[60]fullerene 2∶1 complex can be deposited on an anion-coated gold surface as a monolayer (or at least as a monolayer-like ultra-thin film); as expected, this membrane efficiently shows a redox response in cyclic voltammetry and a photoelectrochemical response under visible light irradiation.
