苯并[de]蒽-7-酮类叔芳胺的合成及其发光性能的研究

Synthesis of Diarylamino-benzo[de]anthracen-7-ones and Their Light Emitting Property

芳基伯胺与芳基溴在Pd(dba)2/P(t-Bu)3催化下于80℃甲苯溶液中反应生成芳基仲胺,芳基仲胺再与3-溴苯并[de]蒽-7-酮在Pd(OAc)2/P(t-Bu)3催化下于120℃邻二甲苯溶液中反应生成苯并[de]蒽-7-酮类叔芳胺有机电致发光材料;3-二苯基氨基苯并[de]蒽-7-酮与丙二腈反应生成2-(3-二苯基氨基)苯并[de]蒽-7-基亚基丙二腈.产物的结构经1HNMR,13CNMR,13C(DEPT),HRMS光谱所证实.用UV-Vis,PL,DSC测定了化合物的发光性能.

The primary arylamines reacted with aryl halides to give the secondary arylamines by the catalysis of Pd（dba）2/P（t-Bu）3 at 80 ℃ in toluene. The secondary arylamines reacted with 3-bromo-benzo[de]- anthrax-cen-7-one to afford the organic light-emitting device （OLED） material of diarylamino- benzo[de]anthracen-7-ones type by the catalysis of Pd（OAc）2/P（t-Bu）3 at 120 ℃ in o-xylene. Reaction of 3-diphenylamino-benzo[de]anthracen-7-one with malononitrile gives 2-（3-diphenylamino-benzo[de]- anthracen-7-ylidene）-malononitrile. The product structures were demonstrated by ^1H NMR, ^13C NMR, ^13C （DEPT）, HRMS spectra. Light emitting properties were examined by UV-vis, PL and DSC spectra.
