Red organic electroluminescent compounds containing bis-condensed DCM derivatives, a method for synthesizing the same and an organic electroluminescent device using the same. The red organic electroluminescent compound having the formula: wherein R1, R1', R2 and R2' are independently hydrogen atom, or C1-C30 alkyl, aryl or hetero ring; R3, R3', R4 and R4' are independently hydrogen atom, C1-C10 alkyl or alkoxy; one or more pairs selected from the group consisting of R1 and R3, R1' and R3', R2 and R4, and R2' and R4' can be connected in forms of -R1-R3-, -R1'-R3'-, -R2-R4-, and -R2'-R4'-; R5, R5', R6 and R6' are independently hydrogen atom, or C1-C30 alkyl, alkoxy or aryl; at least one of R3, R3', R4, R4', R5, R5', R6 and R6' is not hydrogen atom.
