Claim 1:
2. An organic electroluminescent device containing a compound represented by formula (1):, wherein
Z and Z′ identically or differently represent CH, N or C—CN, wherein at least one Z group represents N or at least one Z′ group represents N;
Ar1, Ar2, Ar1′, Ar2′, and Ar4 each independently represent hydrogen atom, substituted or unsubstituted aryl with 6 to 30 carbon atoms, or substituted or unsubstituted heteroaryl with 5 to 30 carbon atoms; Ar4 further represents linear or branched alkyl with 1 to 10 carbon atoms;
Ar3 and Ar5 each independently represent single-bond, substituted or unsubstituted arylene with 6 to 30 carbon atoms, or substituted or unsubstituted heteroarylene with 5 to 30 carbon atoms;
Ar3 further represents linear or branched alkyl with 1 to 10 carbon atoms, substituted or unsubstituted aryl with 6 to 30 carbon atoms, or substituted or unsubstituted heteroaryl with 5 to 30 carbon atoms;
X represents carbon atom, oxygen atom or sulfur atom;
when X represents carbon atom, k=1, m and n each independently represent 0 or 1, and m and n are different;
when X represents oxygen atom or sulfur atom, k=0, m=0, n=1, wherein the organic electroluminescent device comprises at least one functional layer containing the compound, wherein the organic electroluminescent device comprises a hole block layer or an electron transport layer, wherein the hole block layer or the electron transport layer contains the compound.
