摘要:
A novel triarylamine compound having a bipolar property is provided. The triarylamine compound can be used for a hole-injection layer, a hole-transport layer, a light-emitting layer, or an electron-transport layer in a light-emitting element. The triarylamine compound can also be used as a host material with a light-emitting material which emits relatively short-wavelength light, in a structure where the host material and the guest material constitute a light-emitting layer. The triarylamine compound of the present invention is a fluorescent compound and therefore can also be used as a light-emitting substance of a light-emitting layer. A light-emitting element having high emission efficiency is provided. A light-emitting device, an electronic device, or a lighting device having low power consumption is provided.

The present invention provides dyes, reactive dyes and labeled reagents that may be used in the detection or quantification of desirable target molecules, such as proteins and nucleic acids. Dyes are provided that may be used free in solution where the binding of the dye to the target molecule provides signal generation. Dyes are also provided that comprise reactive groups that may be used to attach the dyes to probes that will bind to desirable target molecules. The novel dyes of the present invention have been modified by the addition of charged and polar groups to provide beneficial properties.

摘要:
Disclosed is a novel organic semiconductor material which has a twisted quaterphenylene skeleton as a central unit and simultaneously possesses a skeleton having an electron-transporting property and a skeleton having a hole-transporting property at the terminals of the quaterphenylene skeleton. Specifically, the organic semiconductor material has a [1,1′:2′,1″:2″,1′″]quaterphenyl-4-4′″-diyl group, and one of the terminals of the [1,1′:2′,1″:2″,1′″]quaterphenyl-4-4′″-diyl group is bonded to a skeleton having an electron-transporting property such as a benzoxazole group or an oxadiazole group. A skeleton having a hole-transporting property such as diarylamino group is introduced at the other terminal. This structure allows the formation of a compound having a bipolar property, a high molecular weight, an excellent thermal stability, a large band gap, and high triplet excitation energy.
