An organic light-emitting diode device of the present invention comprises a cathode, an anode, and an organic layer. The organic layer comprises a compound having a structure of formula (I), wherein Ar is an N-aryl carbazole, R and R2 are independently selected from hydrogen, a C1-C4 alkyl substituted or unsubstituted by a C1-C4 alkyl, a C2-C4 alkylene substituted or unsubstituted by a C1-C4 alkyl, a C2-C4 alkynyl substituted or unsubstituted by a C1-C4 alkyl, a C6-C10 aryl or aromatic hydrocarbon group substituted or unsubstituted by one or more substituents R1, and a C5-C8 heteroaryl that contains one or more heteroatoms and is substituted or unsubstituted by one or more substituents R1, and R1 is independently selected from fluorine (F), chlorine (Cl), bromine (Br), iodine (I), cyano (CN), and a C1-C4 alkyl. Because an organic host material used in the present invention has a high glass transition temperature and a high thermal stability, a prepared organic light-emitting device has good and stable performance.
