The present invention relates to novel organic electroluminescent compounds, organic electroluminescent devices and organic solar cells comprising the same. Specifically, the organic electroluminescent compounds according to the invention are represented by Chemical Formula (1) :n nwherein, R 1 and R 2 independently represent hydrogen, deuterium, linear or branched (C1-C20)alkyl, (C2-C20)alkenyl, (C2-C20)alkynyl, (C3-C15)cycloalkyl, tri(C1-C20)alkylsilyl, di(C1-C20)alkyl(C6-C20)arylsilyl, tri(C6-C20)arylsilyl, adamantyl, (C7-C15)bicycloalkyl or (C4-C20)heteroaryl, and the alkyl, alkenyl, alkynyl, cycloalkyl, trialkylsilyl, dialkylarylsilyl, triarylsilyl, adamantyl, bicycloalkyl or heteroaryl of R 1 and R 2 may be further substituted by one or more substituent(s) selected from deuterium, linear or branched (C1-C20)alkyl, (Cl-C20)alkenyl, (C1-C20)alkynyl, halogen, phenyl, fluorenyl, naphthyl and anthryl. n The electroluminescent compounds according to the present invention are green electroluminescent compounds, of which the luminous efficiency and device lifetime have been maximized. |
