An organometallic approach for ultrathin SnO(x)Fe(y)S(z) plates and their graphene composites as stable anode materials for high performance lithium ion batteries.

Through an organometallic approach, ultrathin SnO(x)Fe(y)S(z) plates with ~2 nm single layer-thicknesses were obtained and their graphene composites showed very promising discharge capacities of up to 736 mA h g(-1) and excellent stabilities as anode materials in lithium ion batteries.

Bis(imidazoline-2-thione)-copper(I) catalyzed regioselective boron addition to internal alkynes.

New catalytic systems based on a bis(1,3-disubstituted imidazoline 2-thione)-copper complex have been developed for the highly regioselective boration of internal alkynes.

One-dimensional organometallic molecular wires via assembly of Rh(CO)2Cl(amine): chemical control of interchain distances and optical properties.

The assembly of Rh(CO)(2)Cl(amine) via molecular orbital symmetry interactions, resulting in the formation of one-dimensional molecular wires, has been discovered. The assembly behavior was quite dependent on the type of amine. The interchain distances and optical properties could be controlled by changing the length of the alkyl chain in the amine. We believe that this discovery can be applied not only to preparing more diverse one-dimensional molecular wires via the introduction of predesigned amines but also to gaining a deeper understanding of the physical properties of molecular metals.

Shape-controlled synthesis of silver sulfide nanocrystals by understanding the origin of mixed-shape evolution.

The shape of silver sulfide nanomaterials was successfully controlled by understanding the origin of the mixed-shape problem.

Phase-controlled one-dimensional shape evolution of InSe nanocrystals.

Cubic-phase InSe nanowires were synthesized. Obtaining an appropriate high reaction temperature for formation of nanocrystals using poor solubility of Se powder in oleylamine induced the generation of unusual cubic phase of InSe to form nanowires. In comparison, hexagonal-phase nanoplates were formed by dissolving Se powder in oleylamine before increase of reaction temperature. The diameter of highly monodisperse wires was controlled by varying the amount of Se.

Self-supported organometallic rhodium quinonoid nanocatalysts for stereoselective polymerization of phenylacetylene.

Heterogeneous self-supported organometallic nanocatalysts (ONs) were synthesized by treatment of the eta6-pi-hydroquinone rhodium complex [(1,4-hydroquinone)Rh(COD)]+ with Al(Oi-Pr)3. The organometallic nanocatalysts, the size of which can be controlled by alteration of the reaction conditions, show high catalytic activities in the stereoselective polymerization of phenylacetylene to produce cis-poly(phenylacetylene). A key feature of the ON catalyst synthesis is a facile eta6 to eta4 hapticity change occurring in the quinonoid ring, which is triggered by deprotonation of the -OH groups by Al(Oi-Pr)3, with concomitant coordination of the quinone oxygen atoms to the aluminum.
