| Research Abstract |
The results are summarized as follows.
New electroactive gold nanoparticles containing terathiafulvalene (TTF-Au nanoparticles) of 2-4 nm diameter have been prepared by a reaction of octanethiol-derivatized gold nanoparticles with a tetrathiafulvaleny-monothiol. Immersion of a gold electrode in a solution of the colloidal TTF-Au nanoparticles deposited the colloid films of them on the electrode surface which were remarkable stable under repeated electrochemical cycling. Thus, the TTF-Au nanoparticle films were firmly immobilized on the electrode by a simple self-assembly method without use of terminal ligand like bifunctional aminosiloxane or mercaptosiloxane.
Octanethiol-stabilized gold nanoparticles were treated with a new fullerene CィイD260ィエD2-terminated alkanethiol (1) to give the monodispersed fullerenethiol-functionalized gold nanoparticles (CィイD260ィエD2-Au nanoparticles) of 2 nm diameter with a very narrow size distribution. Immersion of a gold electrode in a solution of CィイD260ィエD2-Au nanoparticles deposited the colloid films of them on the electrode surface which showed two distinct reversible reduction/oxidation waves and significant electrochemical stability. The CィイD260ィエD2-Au nanoparticle films were firmly immobilized on the planar electrode by a simple self-assembly method without use of terminal ligand like bifunctional aminosiloxane or mercaptosiloxane. The electrochemical responses for the CィイD260ィエD2-Au nanoparticle films and self-assembled monolayers of CィイD260ィエD2-thiol 1 adsorbed on gold electrodes are significantly different.
