Double Metallocene Nanowires

Journal of the American Chemical Society, 2009
The structural, electronic, and magnetic properties of double metallocene nanowires PnM(2) (Pn = C(8)H(6), M = V, Cr, Mn, Co, and Ni) are investigated within the framework of gradient-corrected density functional theory. The PnMn(2) nanowire is predicted to be ferromagnetic while other nanowires are either antiferromagnitic or nonmagnetic. In addition,

Polyethylene waxes by metallocenes

Polymers for Advanced Technologies, 2011
AbstractThe syntheses of low‐molecular‐weight polyethylene (PE), in the presence of catalysts based on five different metallocene frameworks, have been compared. High yields and low molecular masses, typical of industrially relevant PE waxes, can be easily achieved by using overpressure of hydrogen.

The Photochemistry of Metallocenes

Russian Chemical Reviews, 1984
The problems of the photochemistry of the dicyclopentadienyl derivatives of Group VIII metals are considered. Examples of the use of the photochemical reactions of metallocenes for the preparation of light-sensitive materials, inhibitors of the photo-ageing of polymers, catalysts of the photodecomposition of polymers, etc. are presented.

Hard versus Soft Materials as Supports for Metallocene and Post‐Metallocene Catalysts

Macromolecular Reaction Engineering, 2009
AbstractThe influence of organic supports on the polymerization behavior of post‐metallocene catalysts is studied and compared with similarly supported titanium and zirconium metallocenes. The effects of the immobilization, activation, and polymerization process were studied by video microscopy, laser confocal fluorescence microscopy, SEM, and TEM.

Chemical and electrochemical oxidation of metallocenes, reactions of metallocenes with mercury salts

Journal of Organometallic Chemistry, 1974
Abstract The products of chemical and electrochemical oxidation of metallocenes, (C 5 H 5 ) 2 M (M  Fe, Ru, Os), were investigated. (C 5 H 5 ) 2 Fe on Pt and Hg anodes was oxidized to the ferricenium cation while the electrolysis of osmocene on Pt electrode led to the previously unknown (C 5 H 5 ) 2 Os o BF 4 − salt and oxidation of ruthenocene ...
