摘要:

发现了空间接近的双温勒伯(Weinreb)酰胺与格氏试剂在温和条件下的单取代反应, 该反应普适性强、 操作简便且产率高, 反应存在动力学控制和热力学控制2种产物. 机理分析表明, 该反应发生了分子内亲核取代反应, 并生成了稳定的单取代中间体, 从而避免了双取代反应的发生. 通过该反应制备了一系列4-取代酞嗪酮类化合物, 合成了基于酞嗪基团的纯红光三环金属化铱(Ⅲ)配合物, 采用该配合物制备的有机电致发光器件表现出高效率[最大外部量子效率(EQEmax)=10.3%]和低浓度猝灭性能.

Abstract:

A monoaddition reaction of spatially close diamides and Grignard reagents under mild conditions was found. In some case, kinetic-controlled products and thermodynamic-controlled products were obtained at the same time. The key step involved an intramolecular nucleophilic reaction. 4-Substituted phthalazinones were conveniently synthesized by this method. Pure red-light-emitting tris-cyclometalated iridium(Ⅲ) complex based on phthalazine building blocks that exhibit high efficiency[maximum external quantum efficiency(EQEmax)=10.3%] had also been synthesized.

Key words: Phthalazinone, Bis-Weinreb amide, Grignard reagent, Iridium(Ⅲ) complex, Organic light-emitting diode(OLED)
