Abstract: The present invention provides an organic electroluminescence device capable of having not only a device lifetime comparable to that of an existing organic electroluminescence device but also a small thickness of smaller than 10 ?m and excellent flexibility. The present invention relates to an organic electroluminescence device having a structure including: an anode; a cathode on a substrate; and a laminate of multiple layers between the anode and the cathode, the device having a thickness of smaller than 10 ?m.

Abstract: The present invention provides a light cosmetology or light therapy light-emitting sheet having excellent conformability to the skin and excellent wearing feeling. The present invention relates to a light cosmetology or light therapy organic electroluminescence sheet used in light cosmetology or light therapy application, the organic electroluminescence sheet including an organic electroluminescence device having a structure in which multiple layers are laminated on a sheet-like flexible substrate and having a thickness of 10 to 100 ?m.

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.
