Abstract: The present invention aims to provide a method capable of easily and efficiently producing a vinyl ether group-containing (meth)acrylic acid ester polymer. The present invention relates to a method of producing a vinyl ether group-containing (meth)acrylic acid ester polymer, the method including group-transfer polymerizing a monomer component containing a vinyl ether group-containing (meth)acrylic acid ester represented by the following formula (1), in the presence of a carbon-carbon double bond-containing silane compound and a catalyst, wherein R1 is a hydrogen atom or a methyl group; R2 and R3 are the same as or different from each other and are each a hydrogen atom or an organic group; R4 is a hydrogen atom or an organic group; and n is an integer of 1 or more.

Abstract: The present invention provides an organic thin film that imparts an excellent electron injection property and an excellent electron transport property when it is used as an electron injection layer of an organic EL device, a coating composition suitable for producing the organic thin film, and an organic EL device material for the organic thin film and the coating composition.

Abstract: The present invention aims to provide an organic thin film that imparts an excellent electron injection property and an excellent electron transport property when it is used as an electron injection layer of an organic EL device. The present invention relates to an organic thin film, which is a single film containing a first material which is a hexahydropyrimidopyrimidine compound having a structure of the following formula (1) and a second material which transports electrons, or a laminate film including a film containing the first material and a film containing the second material, wherein R1 is an optionally substituted aromatic hydrocarbon group, an optionally substituted aromatic heterocyclic group, an optionally substituted arylalkylene group, an optionally substituted divalent to tetravalent acyclic or cyclic hydrocarbon group, a group of a combination of two or more of these groups, or a group of a combination of one or more of these groups and a nitrogen atom; and n is an integer of 1 to 4.

Abstract: An organic thin film that imparts an excellent electron injection property when it is used as an electron injection layer of an organic EL device and a method for producing the organic thin film are provided. An organic thin film at least includes: a first material which is an organic material having an acid dissociation constant pKa of 1 or greater; and a second material which transports an electron. The first material is at least one selected from the group consisting of tertiary amines, phosphazene compounds, guanidine compounds, heterocyclic compounds containing an amidine structure, hydrocarbon compounds having a ring structure, and ketone compounds.

Abstract: The present invention provides novel boron compounds which are useful, depending on their characteristics, as light-emitting materials, electron-transport materials, electron-injection materials, hole-blocking materials, or organic semiconductor materials, and which have new molecular structures quite different from those of the heretofore known boron compounds; their production processes; and functional electronic devices using the same. The novel boron compounds are, for example, those of the following formula (1): These boron compounds can be produced by, for example, reacting boron compounds of the following formula (4): with compounds of the following formula (5): in the presence of a catalyst containing at least one metal element selected from the group consisting of palladium, platinum, and nickel. These boron compounds are used for the functional electronic devices.
