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.
本发明公开了合成基于2,2'-双取代9,9'-螺联苯的三芳基二胺的方法。首先提供2,2'-二氨基-9,9'-螺联苯、辅助Pd催化剂和芳基卤素BX,其中X选自以下组中的一组:Cl、Br和I,B包括以下一组之一:芳基基团、杂环、多重融合环、带有杂原子的多重融合环。接下来进行取代反应,使2,2'-二氨基-9,9'-螺联苯与芳基卤素BX反应,从而产生2,2'-双取代9,9'-螺联苯基三芳基二胺。此外,本发明还公开了包含2,2'-双(N,N-二取代氨基)-9,9'-螺联苯的空穴传输材料的有机发光装置。
