The present invention discloses synthesis of 2,2′-disubstituted 9,9′-spirobifluorene-based triaryldiamine. First, 2,2′-diamino-9,9′-spirobifluorene, a Pd-catalyst as auxiliary and aryl halide BX are provided, wherein X is selected from the group consisting of: Cl, Br and I, B comprises one of the following group: aryl moiety, hetero cycle, multiple fused ring, multiple fused ring with hetero atom(s). Next, a substitution reaction is performed to react the 2,2′-diamino-9,9′-spirobifluorene with the aryl halide BX to produce the 2,2′-disubstituted 9,9′-spirobifluorene-based triaryldiamines. In addition, the present invention discloses organic light emitting devices comprising hole transporting material comprising 2,2′-bis(N,N-disubstituted amino)-9,9′-spirobifluorenes.
