Preferred Definitions:    Ar1,Ar2=optionally substituted cyclic aromatic group such as 1-naphthyl, 9-phenanthryl, pyrenyl, or 2-fluorenyl group, more preferably Ar1,Ar2 is phenyl, 4-methylphenyl or 4-biphenylyl, and Ar3 is phenyl, 3,5-diphenyl phenyl, 1-naphthyl, 4-biphenylyl, 4-terphenyl, 9-anthryl, 10-phenyl -9-anthryl or 10-(3,5-diphenyl phenyl)-9-anthryl group;    M=phenylene, 1,4-naphthalene diyl, 2,6-naphthalene diyl, 4,4'-biphenyl diyl, 4,4'-terphenyl diyl, 9,10-anthracenediyl or 2,7-9,9'-dialkylfluorene diyl, preferably M is chosen from 6 groups of formula (2a-2c), or single bond; and    R1,R2=hydrogen atom.    SPECIFIC COMPOUNDS - 117 Specific amine compounds (e.g. compound 1) of general formula (1) are disclosed.    EXAMPLE - 2,7-Dibromo-9,9'-bis(4-(2-methoxy ethoxymethoxy)phenyl)-9H-fluorene (in g) (3), diphenyl amine (1.5), sodium-tert-butoxide (1.01) and xylene (20 ml) were added to a flask. Palladium acetate (4 mg) and tri-tert-butyl phosphine (10 mg) were added and heated at 120degreesC, and stirred for 3 hours. 30 ml of water was added after cooling to room temperature, and organic phase was separated and concentrated, and 2,7-bis(diphenyl amino)-9,9'-bis(4-(2-methoxy ethoxymethoxy)phenyl)-9H-fluorene (2.8) was obtained. The obtained compound was dissolved in dichloromethane and added with 5 ml of 6N hydrochloric acid aqueous solution, and reacted at room temperature for 5 hours. Water was added, organic phase was separated and added with pyridine and trifluoromethane sulfonic acid anhydride (3.1) and stirred at room temperature. Water was added, organic phase was separated and concentrated, and 2,7-bis(diphenyl amino)-9,9'-bis(4-(trifluoromethane sulfonyloxy)phenyl)-9H-fluorene was obtained. The obtained compound (1.0), phenyl boronic acid (0.13), 20% sodium carbonate (5), tetrakis triphenyl phosphine palladium (20) and tetrahydrofuran were added to a reaction container and refluxed for 2 hours. The organic layer was separated and concentrated, and amorphous amine compound (1) of formula (15) was obtained. The compound had glass transition point at 135degreesC. An organic electroluminescent element having hole-transport layer formed using the synthesized compound, was produced. The element showed brightness of 500 cd/m2 at current density of 8 mA/cm2. The electric current-brightness characteristics of the element was measured after maintaining at 90degreesC under vacuum for 100 hours, and found that the characteristics were hardly changed.
