TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (disclosed): 2,8-dibromochrysene is aminated by diaryl amine, to obtain aromatic-amine derivative (1). Preferred Component: The aromatic-amine derivative is blue-type luminescent material. The organic electroluminescent element comprises organic thin film layer having single layer or multiple layers containing light emitting layer provided between anode and cathode. Preferred Composition: The organic thin film layer comprises aromatic-amine derivative. The light emitting layer comprises aromatic-amine derivative as doping material, and anthracene derivative of formula (3) or pyrene derivative of formula (4), as host material.A1,A2=group derived from 6-20C optionally substituted aromatic ring;R1-R8=6-50C aryl, 4-50C heteroaryl, 1-50C alkyl, 3-50C cycloalkyl, 1-50C alkoxy, aralkyl, 5-50C aryloxy, 5-50C aryl thio, alkoxycarbonyl or silyl (all optionally substituted), H, carboxyl, halo, cyano, nitro or hydroxyl;Ar5-Ar6=optionally substituted 6-50C aryl;L1,L2=phenylene, naphthalenylene, fluorenylene or dibenzosilolylene (all optionally substituted);s,q=0-2;p=1-4;andr=0-4.The alkyl portion of aralkyl and alkoxy carbonyl is 1-50C alkyl. The aryl portion of aralkyl is 6-50C aryl. L1 or Ar5 is coupled with pyrene in 1-5 position. L2 or Ar6 is coupled with pyrene in 6-10 position. When p+r is even number, Ar5, Ar6, L1 and L2 is Ar5 and Ar6 and/or L1 and L2 are same or different. When Ar5=Ar6 and L1=L2, s and q and/or p and r are same or different. When s=q and p=r, L1 and L2 or Ar5 and Ar6 are coupled in same or different positions of pyrene. L1 and Ar5 are not substituted in 1 and 6 position of pyrene, and L2 and Ar6 are not substituted in 2 and 7 position of pyrene. Preferred Definitions:    Ar1-Ar4=4-(2-phenylpropane-2-yl)phenyl group (2).    -NAr1Ar2 is coupled at 2 or 6-position of chrysenylene group and -NAr3Ar4 is coupled at 8 or 12-position of chrysenylene group.    SPECIFIC COMPOUNDS - 6 aromatic-amine derivatives are disclosed such as N,N,N',N'-tetrakis-(4-(1-methyl-1-phenyl-ethyl)-phenyl)-chrysene-6,12-diamine of formula (1a), N,N'-bis-(4-(1-methyl-1-phenyl-ethyl)-phenyl)-N,N'-di-naphthalen-2-yl-chrysene-6,12-diamine, N-(6,7-dimethyl-naphthalen-2-yl)-N'-(3,4-dimethyl-phenyl)-N,N'-bis-(4-(1-methyl-1-phenyl-ethyl)-phenyl)-chrysene-6,12-diamine, N,N'-bis-(4-(1-methyl-1-phenyl-ethyl)-phenyl)-N-(6-trimethylsilanyl-naphthalen-2-yl)-N'-(4-trimethylsilanyl-phenyl)-chrysene-6,12-diamine and N,N,N',N'-tetrakis-(4-(1-methyl-1-phenyl-ethyl)-phenyl)-chrysene-2,8-diamine.    EXAMPLE - 6,12-dibromo chrysene (in g) (3.8), bis(4-(2-phenylpropane-2-yl)phenyl)amine (10.1), palladium acetate (0.03), tri-t-butyl phosphine (0.06), sodium-t-butoxide (2.4) and dry toluene (100 ml) were mixed, heat-stirred at 100 degrees C overnight, filtered the precipitated crystal and washed using toluene (50 ml) and methanol (100 ml), to obtain N,N,N',N'-tetrakis-(4-(1-methyl-1-phenyl-ethyl)-phenyl)-chrysene-6,12-diamine (1a).
