The invention relates to the technical field of organic photoelectric materials, in particular to an organic compound and an organic electroluminescent device using the same. The organic compound has a structure as shown in a formula I: # imgabs0 #, wherein X1 and X2 are the same and are selected from O, S or C (CH3) 2; the A group and the B group are respectively and independently selected from a group consisting of hydrogen, phenyl and C1-C10 alkyl; r1 to R4 are respectively and independently selected from hydrogen and alkyl groups with 1 to 10 carbon atoms. When the compound is used as a luminescent material in an OLED device, the compound shows excellent device performance and stability. The invention also protects the organic light-emitting device adopting the compound with the general formula. 本发明涉及有机光电材料技术领域，具体涉及一种有机化合物及其使用该化合物的有机电致器件。所述的有机化合物具有如下式I所示的结构：#imgabs0#其中，X1、X2相同的选自于O、S或C(CH3)2；所述A基团、B基团各自独立的选自由氢、苯基、C1-C10烷基所组成的组；所述R1-R4各自独立地选自氢、C1-C10烷基。本发明的化合物作为OLED器件中的发光材料时，表现出优异的器件性能和稳定性。本发明同时保护采用上述通式化合物
