Document Type and Number:
Japanese Patent JP4213832
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a new compound being a triarylamine compound containing a specific substituent, useful as an organic luminous element material capable of being luminous in high brightness in high efficiency from green to red at a low applied voltage. SOLUTION: This compound is shown by formula I [R1 and R2 are each a (substituted) aryl, a heterocyclic group, an aliphatic hydrocarbon group, at least one of R1 and R2 is an aryl or a heterocyclic group; R3 is a substituent; m is 0-4; R4 to R6 are each H or a substituent; Z127 is a 5- to 7-membered ring-forming atomic group (e.g. substituted 1,3-indanedione nucleus or the like; n is 0-2) such as a triarylamine compound of formula II. The compound of formula II is obtained by dissolving 4-(N,N-diphenylamino)benzaldehyde and 5-phenylindane-1,3-dione 2 in ethanol, adding piperidine, refluxing the solution under heating, cooling the reaction solution, purifying precipitated crude crystal by silica gel chromatography and crystallizing the compound by ethanol- chloroform.
