TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (disclosed): Compound (I) is obtained by coupling a halogenated tetraphenyl phenylenediamine of formula (II) and a boronic acid compound of formula: X-B(OH)2 in the presence of a catalyst.Y'=halo;X=R1-R20 or X1-X4;andm=0 or 1, with at least two m being 1.Preferred Property: The orientation parameter (S) of the thin film formed using the amine compound as defined by the angle ( theta ) made by the molecular axis inside a thin film formed on a substrate and the substrate normal line direction, and the extinction coefficients (ko,ke) of the substrate parallel direction and orthogonal direction obtained by multi-incident angle spectroscopy ellipsometry measurement of the thin film is -0.5 to -0.15, and is calculated using a relationship given by, S = (3cos2( theta )-1), which is greater than 1/2 and less than or equal to (ke-ko)/(ke+2ko). SPECIFIC COMPOUNDS - 24 Compounds (I) are disclosed e.g. N,N,N',N'-tetrakis-(4-benzo(b)thiophen-2-yl-phenyl)-benzene-1,4-diamine of formula (IA), N,N'-bis-biphenyl-4-yl-N,N'-bis-(4-thiophen-2-yl-phenyl)-benzene-1,4-diamine, N,N-bis-biphenyl-4-yl-N',N'-bis-(4-thiophen-2-yl-phenyl)-benzene-1,4-diamine, N-phenyl-N,N',N'-tris-(4-thiophen-2-yl-phenyl)-benzene-1,4-diamine, and N,N,N',N'-tetrakis-(4-thiophen-2-yl-phenyl)-benzene-1,4-diamine.    EXAMPLE - (In g) 1,4-bis(di-(4-bromophenyl)amino)benzene (0.5) was taken in a flask under argon air flow, and 2-benzothiophene boronic acid (0.72), tetrakis(triphenylphosphine)palladium (0.047), tetrahydrofuran (50 ml), and 20M potassium carbonate aqueous solution (6.6 ml) were added and heat-refluxed for 48 hours. Pure water was added after cooling to room temperature and the reaction mixture was extracted using dichloromethane twice. The extraction liquid was washed with pure water and concentrated under reduced pressure after drying. The obtained solid was recrystallized using toluene, to obtain N,N,N',N'-tetrakis-(4-benzo(b)thiophen-2-yl-phenyl)-benzene-1,4-diamine (0.41) with a yield of 62%. The compound provided organic electroluminescent element having a drive voltage of 6 V with respect to an applied current of 20 mA/cm2.
