Title:
AMINE COMPOUND
Document Type and Number:
Japanese Patent JP3714980
Kind Code:
B2
Abstract:
PURPOSE: To provide a new amine compound capable of easily forming a vitreous state and stably keeping the state and having thermal and chemical stabilities and, accordingly, useful as a charge transfer material to be used in an organic electroluminescent element such as an electrophotographic receptor.
CONSTITUTION: This amine compound is expressed by formula I (R1, R2 and R3 are each independently H, an alkyl, an aryl, etc.; R4 is H, an alkyl, Cl, etc.; A1 is group of formula II, etc.), e.g. the compound of formula III. The compound can be produced e.g. by condensing 2 equivalents of the corresponding triphenylbenzidine compound with 1 equivalent of a dihalogenated compound or condensing an N,N'-diacetyl compound of the corresponding diamino compound with a 4'-halogenated biphenylylacetanilide compound, hydrolyzing the condensation product and condensing the product with an aryl halide. These condensation reactions are preferably carried out in the absence of solvent or in a solvent such as nitrobenzene at 160-230°C using calcium carbonate as a deacidification agent and copper powder, etc., as a catalyst.
