利用四苯基甲烷中碳原子特殊的sp~3轨道杂化结构来打断并控制分子内共轭程度,并采用硅原子替换四苯基甲烷中的碳原子合成四苯基硅烷.将这两种结构作为核,在其四周以四苯乙烯(TPE)或三苯乙烯(tri PE)修饰,设计并合成了六个具有聚集诱导发光(AIE)效应的小分子.这些分子均可以溶解在常见有机溶剂中并具有良好的热稳定性.通过溶液旋涂法将其应用到有机电致发光器件(OLED)中,得到最好的器件效率为亮度最大值(L_(max))1730 cd·m~(-2),电流效率最大值(Lmax)2.21 cd·A请下载后查看，本文暂不支持在线获取查看简介。(-1),功率最大值(η_(p,max))0.77 lm·W~(-1),外量子效率最大值(η_(ext,max))1.01%.
The special sp ~ 3 orbital hybrid structure of carbon atoms in tetraphenyl methane is used to interrupt and control the degree of intramolecular conjugation, and the silicon atoms are used to replace the carbon atoms in tetraphenyl methane to synthesize tetraphenylsilane. As a core structure, six small molecules with aggregate-induced luminescence (AIE) effects were designed and synthesized by tetraphenylethylene (TPE) or tri PE. All these molecules can be dissolved in common Organic solvent and has good thermal stability.It was applied to organic electroluminescent devices (OLEDs) by solution spin-coating to obtain the best device efficiency of the maximum brightness (L_ (max)) of 1730 cd · m ~ (-2), maximum current efficiency (Lmax) 2.21 cd · A Please download to view, this article is not available for online view profile.
