Mechanochemical lithiation of layered polysilane.
Lithiated polysilane was synthesized by the mechanochemical reaction of layered polysilane with metallic lithium. The resulting dark green powder formed a Si-Li bond on the surface and demonstrated electroconductivity.
متن کاملHessian Biased Force Field for Polysilane Polymers
We report a force field (FF) suitable for molecular dynamics simulations of polysilane polymers. This FF, denoted MSXX, was developed using the Hessian biased method to describe accurately the vibrational states, the a b initio torsional potential energy surface, and the ab initio electrostatic charges of polysilane oligomers. This MSXX FF was used to calculate various spectroscopic and mechani...
متن کاملAmphiphilic polysilane-methacrylate block copolymers — Formation and interesting properties —
Several polysilane block copolymers have been prepared by the newly developed method, anionic polymerization of masked disilenes. Especially amphiphilic block copolymers of poly(1,1-dimethyl-2,2-dihexyldisilene) and poly methacrylate are focused. Poly(1,1-dimethyl-2,2-dihexyldisilene)-b-poly(2-hydroxyethyl methacrylate) (PMHS-b-PHEMA) is the first example of the amphiphilic polysilane copolymer...
متن کاملContinuous flow hydrogenation using polysilane-supported palladium/alumina hybrid catalysts
Continuous flow systems for hydrogenation using polysilane-supported palladium/alumina (Pd/(PSi-Al(2)O(3))) hybrid catalysts were developed. Our original Pd/(PSi-Al(2)O(3)) catalysts were used successfully in these systems and the hydrogenation of unsaturated C-C bonds and a nitro group, deprotection of a carbobenzyloxy (Cbz) group, and a dehalogenation reaction proceeded smoothly. The catalyst...
متن کاملFlow Polynomial of some Dendrimers
Suppose G is an nvertex and medge simple graph with edge set E(G). An integervalued function f: E(G) → Z is called a flow. Tutte was introduced the flow polynomial F(G, λ) as a polynomial in an indeterminate λ with integer coefficients by F(G,λ) In this paper the Flow polynomial of some dendrimers are computed.
