摘要:构建 C(Sp 2 )-n 键最广泛使用的方法之一是过渡金属催化的芳基卤化物/硼酸与胺的交叉偶联,称为乌尔曼缩合,Buchwald-Hartwig 胺化和 Chan-拉姆联轴器.然而,芳基卤化物/硼酸通常需要多步制备,同时产生大量腐蚀性和有毒废物,使得该反应不太有吸引力.在此,我们提出了一种前所未有的方法,通过buchwald-Hartwig 型反应形成 C(Sp 2 )-n,使用合成上游硝基芳烃作为唯一起始原料,从而消除了对芳基卤化物和预先形成的芳基胺的需要.从硝基芳烃一步获得了多种对称的二芳基胺和三芳基胺,更重要的是,还通过一锅/两步法高选择性地合成了各种不对称的二芳基胺和三芳基胺.此外,放大实验的成功,药物中间体的后期功能化以及空穴传输材料tcta的快速制备展示了该方案在合成化学中的实用性和实用性.机理研究表明,这种转化可能通过硝基芳烃还原原位生成的芳胺中间体进行,随后与另一种硝基芳烃发生脱硝

摘要:The present inventive concept relates to an in situ core/shell perovskite nanocrystal film formed by an in situ nanocrystal synthesis process, a method for producing the same, and a light emitting device comprising the same as a light-emitting layer. The in situ core/shell perovskite nanocrystal film formed by the in situ nanocrystal synthesis process according to the present inventive concept exhibits a strong charge confinement effect by nanocrystal formation, and can simultaneously greatly improve the luminescence efficiency and lifetime by maintaining the fast charge transport capability of polycrystalline perovskite.

摘要:A high-purity organometallic iridium complex is provided. The organometallic iridium complex includes iridium and a plurality of ligands cyclometallated to the iridium. Each of the plurality of ligands includes a heteroaromatic ring having a coordinatable nitrogen atom. In LC analysis of the organometallic iridium complex, an impurity which has a monochlorinated ligand among the plurality of ligands is 0.1% or less by quantitating using peak area count with a PDA detector.

摘要:The present invention is concerned with the provision of screening assays. More specifically it relates to a method to a method for determining whether an exogenous stimulus is capable of eliciting at least one biological response in a host cell comprising the steps of (i) applying the said stimulus to a host cell which comprises a plurality of different polynucleotide constructs each construct comprising a unique expressed tag (EXT) operatively linked to an expression control sequence whose activity can be exclusively modulated by one specific signalling pathway or cellular sensor implemented in said host cell, said signalling pathway or cellular sensor being involved in eliciting a biological response and being sensitive for the exogenous stimulus, (i) determining the amount of at least one expressed tag; and (iii) comparing the amount of the at least one unique expressed tag to a suitable reference amount, whereby it is determined whether the exogenous stimulus is capable of eliciting at least one biological response in the host cell.
