G. published an article in Journal of Physical Chemistry Letters. The title of the article was 《A Fullerene-Platinum Complex for Direct Functional Patterning of Single Metal Atom-Embedded Carbon Nanostructures》.Name: 4,4′-Dimethyl-2,2′-bipyridine The author mentioned the following in the article:
The development of patterning materials (“”resists””) at the nanoscale involves two distinct trends-one is toward high sensitivity and resolution for miniaturization, the other aims at functionalization of the resists to realize bottom-up construction of distinct nanoarchitectures. Patterning of carbon nanostructures, a seemingly ideal application for organic functional resists, has been highly reliant on complicated pattern transfer processes due to a lack of patternable precursors. Here we present a fullerene-metal coordination complex as a fabrication material for direct functional patterning of sub-10 nm metal-containing carbon structures. The attachment of one platinum atom per fullerene mol. not only leads to significant improvement of sensitivity and resolution, but also enables stable at. dispersion of the platinum ions within the carbon matrix, which may gain fundamentally new interest in functional patterning of hierarchical carbon nanostructures. In the part of experimental materials, we found many familiar compounds, such as 4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6Name: 4,4′-Dimethyl-2,2′-bipyridine)
4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6) is used as a chemical Intermediate. It can be used for the determination of ferrous and cyanide compounds.Name: 4,4′-Dimethyl-2,2′-bipyridine Furthermore, 4,4′-Dimethyl-2,2′-bipyridine is used in the synthesis of a series of o-phenanthroline-substituted ruthenium(II) complexes.
