Although gold is the subject of one of the most ancient themes of investigation in science, its renaissance now leads to an exponentially increasing number of publications, especially in the context of emerging nanoscience and nanotechnology with nanoparticles and self-assembled monolayers (SAMs). We will limit the present review to gold nanoparticles (AuNPs), also called gold colloids. AuNPs are the most stable metal nanoparticles, and they present fascinating aspects such as their assembly of multiple types involving materials science, the behavior of the individual particles, size-related electronic, magnetic and optical properties (quantum size effect), and their applications to catalysis and biology. Their promises are in these fields as well as in the bottom-up approach of nanotechnology, and they will be key materials and building block in the 21st century. Whereas the extraction of gold started in the 5th millennium B.C. near Varna (Bulgaria) and reached 10 tons per year in Egypt around 1200-1300 B.C. when the marvelous statue of Touthankamon was constructed, it is probable that “soluble” gold appeared around the 5th or 4th century B.C. in Egypt and China. In antiquity, materials were used in an ecological sense for both aesthetic and curative purposes. Colloidal gold was used to make ruby glass 293 Chem. Rev. 2004, 104, 293−346

Since the discovery of mechanically exfoliated graphene in 2004, research on ultrathin two-dimensional (2D) nanomaterials has grown exponentially in the fields of condensed matter physics, material science, chemistry, and nanotechnology. Highlighting their compelling physical, chemical, electronic, and optical properties, as well as their various potential applications, in this Review, we summarize the state-of-art progress on the ultrathin 2D nanomaterials with a particular emphasis on their recent advances. First, we introduce the unique advances on ultrathin 2D nanomaterials, followed by the description of their composition and crystal structures. The assortments of their synthetic methods are then summarized, including insights on their advantages and limitations, alongside some recommendations on suitable characterization techniques. We also discuss in detail the utilization of these ultrathin 2D nanomaterials for wide ranges of potential applications among the electronics/optoelectronics, electrocat...

Electrochemical synthesis and redox properties of a polyruthenocene electrode film

A new azo-conjugated catecholate ligand, azocat, and its nickel complexes were synthesized, and their physical and chemical properties were investigated. The complex with one azocat shows no obvious photo-response, whereas the compound with two azocat's causes a little photoisomerization. Both of these novel azo-conjugated catecholate complexes show remarkable proton responses.

Electroactive polymer films, prepared by electroreduction of 1,1′-bis(chloromethyl)ferrocene (BCMF) at a glassy carbon electrode in acetonitrile, act as a selective charge-transport mediator for the reduction of redox couples in the ferrocene state and for the oxidation of the couples in the ferricinium state

The reaction of CpCo(PPh3)2, in which Cp=η5-cyclopentadienyl, with a π-conjugated diacetylene, FcC≡C–o-C6H4–C≡CFc, in which Fc=ferrocenyl, was found to give a cyclobutadienecobalt mononuclear complex, {η4-C4Fc2(o-FcC6H4)2}CoCp (1), the crystal structure of which was determined by X-ray crystallography. In contrast, the reaction of CpCo(PPh3)2 with FcC≡C–p-C6H4–C≡CFc affords a cyclobutadienecobalt polymer, [p-C6H4(η4-C4Fc2)CoCp] n (2). The monocobalt complex 1 shows reversible 1e− and 3e− redox waves at E0′=0.116 and 0.350 V vs Ag/Ag+, and the polymer complex 2 shows two chemically reversible redox waves at E0′=0.143 and 0.219 V for the oxidation of the ferrocenyl moieties in the cyclic voltammogram. Crystal data are as follows: (1, C65H49CoFe4), triclinic, space group P\={1} (No. 2), a=13.547(4), b=16.197(4), c=11.763(4) A, α=106.79(2), β=97.93(3), γ=97.12(3), V=2410(1) A3, Z=2.
