  • Patent number: 8436173
    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.
