摘要:
6-Epoxyethyl-3-oxatricyclo[3.2.1.0 2,4 ]octane derivatives and 2,3-epoxy-6-epoxyethyl-1,4;5,8-dimethano-decahydronaphthalene derivatives which are expected to be used as monomers to give plastics having a high transition temperature are easily produced by oxidizing corresponding 6-vinyl compounds with dioxorane.
摘要:
A photovoltaic element produced from a product resulting from decomposition of a silicon polymer having an organic substituent of the group consisting of a hydrocarbon group, a halogenated hydrocarbon group and a silyl group R 3 R 4 R 5 Si- (wherein R 3 - R 5 each are identical or different, including C 1 - C 8 alkyl groups and C 6 - C 10 aryl groups). The inventive photovoltaic element is substantially pollution-free and capable of quantity production at a relatively large unit size.
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:
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.
摘要:
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.
