NOVELTY - An aromatic-amine derivative is new.    USE - New aromatic-amine derivative is useful as hole-transport material or hole-injection material in organic electroluminescent elements (all claimed) used for light sources e.g. backlights, and LCDs of wall-mounted televisions, copiers, printers, measuring instruments, display boards, and marker lamps. Can also be used in electrophotographic photoreceptors, photoelectric conversion elements, solar cells, and image sensors.    ADVANTAGE - The new aromatic-amine derivative provides organic electroluminescent elements which can retain high light-emission efficiency even when exposed to high-temperature atmosphere, and exhibits a low driving voltage and a long emission life. Crystallization of molecule is suppressed. The derivative enables manufacture of organic electroluminescent elements with high yield.    DETAILED DESCRIPTION - An aromatic-amine derivative of formula: N(-Ar1)(-Ar2)(-Ar3), is new.    Ar1=organic group (A) of formula (i) or (ii);    Ar2=organic group (A) or organic group (B) of formula: -(Ar5)(-(R6)d)-(Ar6)(-(R7)e)-(Ar7)(-(R8)f);    Ar3=organic group (A), organic group (B), or organic group (C) of formula: -(Ar8)(-(R11)g);    Ar4=optionally substituted 10-14C condensed-ring group;    R1-R8,R11=H, 1-10C linear, branched or cyclic alkyl, or 6-12C aryl;    L=optionally substituted 6-10C arylene;    a-g=0-2;    R3+R4+R5,R6+R7+R8=saturated ring structure;    Ar5,Ar6=optionally substituted 6-14C arylene;    Ar7=single bond or optionally substituted 6-14C arylene;and    Ar8=optionally substituted 10-14C arylene.    (i) When a, b or c is 2, R3, R4 or R5 may combine with each other to form unsaturated ring structure; and (ii) When d, e or f is 2, R6, R7 or R8 may form unsaturated ring structure. An INDEPENDENT CLAIM is included for organic electroluminescent element consisting of an organic thin film layer having layer(s) comprising a light-emitting layer, clamped between a cathode and an anode. The organic thin film layer(s) contains the aromatic-amine derivative as one component or a mixture.
