摘要:
Polysilanes are produced from hydrosilanes using as a catalyst a mixture of a specific metallocene compound and either a specific silyl compound or a specific metallic hydride. This invention can efficiently provide a polysilane having a higher degree of polymerization than when using a known catalyst.

6-Epithioethyl-3-oxatricyclo [3.2.1.0 2.4 ] octane, a novel compound, is prepared by reaction of the corresponding 6-epoxyethyl-3-oxatricyclo [3.2.1.0 2.4 ] octane with an ammonium or alkali or alkaline earth metal thiocyanate or a thiourea, and is useful as a monomer for preparation of, e.g., heat resistant plastics and plastics for optical use.
摘要:
A method of producing a semiconducting material comprises reacting one or more of halogenosilanes with an alkali metal and/or an alkaline earth metal in an inert solvent to give a condensate and thermally decomposing the condensate. The condensate is dissolved in a suitable solvent such as toluene and tetrahydrofuran and applied by casting to a suitable substrate. The resulting semiconductor material in its film form has an optical band-gap (EO) of usually 0.1-4.0 eV.
摘要:
A method of producing a semiconducting material comprises subjecting a selected class of hydrosilane compounds to hydrogenative condensation in the presence of a catalyst comprising at least one of metals or metal compounds of Group 3B-Group 7B or Group 8 of the Periodic Table, a mixture thereof with a specified silyl compound and/or a specified metal hydride. The resulting condensate is dissolved in a suitable solvent and cast over a quartz or stainless steel substrate, or a silicone wafer to provide a thin film having a specified conductivity and a specified optical band-gap (Eo).
摘要:
A novel epoxy resin containing a norbornane ring is formed by polymerizing a norbornane compound containing an epoxy group in the ring and an epoxyethyl or epithioethyl group bound to the ring. This epoxy resin can be cured in a usual manner. The cured product is, because of the norbornane skeleton, excellent in hardness and strength and low in moisture absorption. Compared to an epoxy resin having an aromatic ring, said epoxy resin is excellent in electrical characteristics since it is free from Na, Cl, etc., and is suited for use in sealing materials of LSI, etc. The compound containing the epithioethyl group is high in refractive index because of the epithioethyl group and can be used also in the optical field.
