摘要:
A process of making an antimony-containing or bismuth containing film such as a germanium-antimony-tellurium alloy (GST) or germanium-bismuth-tellurium (GBT) film uses a process selected from atomic layer deposition and chemical vapor deposition. A silylantimony precursor or silylbismuth precursor is used as a source of antimony or bismuth.
摘要:
A process for the production of living radical polymers, characterized by polymerizing a vinyl monomer by the use of an organotellurium compound represented by the general formula (1) and an azo polymerization initiator; and living radical polymers produced by the process: (1) wherein R1 is C1-8 alkyl, aryl, substituted aryl, or an aromatic heterocyclic group; R2 and R3 are each hydrogen or C1-8 alkyl; and R4 is aryl, substituted aryl, an aromatic heterocyclic group, acyl, oxycarbonyl, or cyano.
摘要:
An organotellurium compound of the formula (1) is useful as a living radical polymerization initiator and makes possible precision control of molecular weights and molecular weight distributions under mild conditions wherein R is C1-C8 alkyl, R and R are each a hydrogen atom or C1-C8 alkyl, and R is aryl, substituted aryl, aromatic heterocyclic group, hydroxycarbonyl or cyano.
摘要:
A process for producing a living radical polymer characterized in that a vinyl monomer is polymerized with use of an organotellurium compound represented by the formula (1) and an azo type polymerization initiator, and the living radical polymer obtainable by the process wherein R 1 is C 1 -C 8 alkyl, aryl, substituted aryl or an aromatic heterocyclic group, R 2 and R 3 are each a hydrogen atom or C 1 -C 8 alkyl, and R 4 is aryl, substituted aryl, an aromatic heterocyclic group, acyl, oxycarbonyl or cyano.
摘要:
A novel series of polycyclic amine derivatives, of formula I methods of making the compounds, novel intermediates, compositions containing them, and pharmaceutical compositions useful in the treatment and prevention of cerebrovascular disorders and useful as anesthetics or analgesics.
摘要:
Novel Z-3-trihalochalcogenpropenone compounds and methods of making such compounds are disclosed. The Z-3- trihalochalcogenpropenone compounds are useful as sensitizers in electrophotographic compositions.
摘要:
A material for lithography containing a tellurium-containing compound or a tellurium-containing resin, a production method therefor, a composition for lithography, a pattern formation method, a compound, a resin, and a method for purifying the compound or the resin.
