Compound having an electron transport properties or electroluminescent characteristics

摘要

Compound ^(CR 3 = ^{CR 4)} nAr of ^(CR 4 = ^{CR 3)}_n R ^2, wherein, n is 1 or 0 the formula ^{R 1,} Ar may be a combination of condensation and chain fused or chain or shows the aryl or heteroaryl having an aromatic ring of 1-5, well, in the case of a five-membered ring, which alkoxy terrorism atoms or aryl, fluoro, fluoro to nitrogen is substituted alkoxy, fluoro, cyano or fluoroalkyl Well is N substituted by aryl which is optionally further substituted by cyano or alkyl; R ² and R ¹ are independently a nitrogen or an aryl having a fused aromatic ring of 2 to 4, a sulfur-containing heteroaryl or an oxygen , one of which is a five-membered ring well, and is optionally substituted by aryl or heteroaryl having a condensed aromatic ring or a chain of 1 to 5, which may be further substituted alkoxy, fluoro, cyano or fluoroalkyl well; ^{R 3} and ^{R 4} is hydrogen, methyl, ethyl or benzyl independently. A method of producing a compound having an electron-conductive properties and electroluminescent properties and / or is provided, which is further substituted by an aryl or heteroaryl having an aromatic ring of 1 to 4 or unsubstituted, aromatic dialdehyde includes be fused with heteroaryl compounds are methyl-substituted with a ring fused 2-4 may, substituents or heterocyclyl substituents or the aryl optionally fluoro one or more cyano substituents or fluoroalkyl be replaced. Under reflux, the condensation is carried out in acetic anhydride. The compounds can be incorporated into the electrostatic imaging member that a high electron mobility, and provides life and good low turn-on voltage in accordance with an embodiment or can for example be incorporated in the optical light-emitting diode as an electron transport layer. Compositions comprising the dopant is provided with at least one electron transport material and a second or host compounds and / or above.
