metallocage was also realized by using two self‐recognizable tritopic building blocks. The photophysical study of the metallo‐supramolecules assembled from the d10 metal ions revealed intense ligand‐based photoluminescence in solution. The self‐assembly strategy described here provides an efficient methodology for building pre‐programmable, sophisticated supramolecular architectures furnished with photoactivity
通过在6,6''-二(2,6-二甲氧基苯基)-取代的和未取代的基于联吡啶的配体的组合下,可以在环境条件下自发形成杂合镉(II)双(叔吡啶)络合物。在这种动态杂合剂络合的基础上,可以很容易地从预先设计的多组分系统中以定量产率组装各种金属-超分子大环化合物和笼子。互补的结扎增强了自我识别能力,有助于将四成分动态库的形状依赖型自分类分为两个明确定义的平行四边形。另外,纯合和杂合复合物之间的微妙的不稳定性导致定点选择性Cd II –Zn IISierpiński三角形中的重金属化。通过使用两个可自我识别的三位构造单元,也可以轻松构建十二面体四面体金属位点。由d 10个金属离子组装而成的金属超分子的光物理研究表明,溶液中存在强的基于配体的光致发光。此处描述的自组装策略为构建具有光活性的可预编程,复杂的超分子体系结构提供了一种有效的方法。
Asymmetric Strecker Reaction of Ketoimines Catalyzed by a Novel Chiral BifunctionalN,N′-Dioxide
A novel bifunctional N,N′-dioxide derived from L-prolinamide was employed to catalyze the enantioselective Streckerreaction of a range of N-tosyl ketoimines, and an effective additive was used to improve the reactivity (up to 99 % yield) as well as the enantioselectivity (up to 91 % ee). In addition, a rational transition state was proposed to elucidate the origin of chiral induction in which an S-adduct
