Abstract
The synthesis and characterization of two direct platinum (1 and 6a/b) and three ethynyl-platinum corannulene derivatives (2, 8 and 9), bearing 2, 4, or 5 square planar platinum centers, are presented. The structure of the bowl bearing substituents remains comparable to corannulene and the dynamic behavior of the bowl inversion as assessed by VT NMR supports a persistent bowl structure in solution. These platinum-corannulenes are well-structured tectons for the future assembly of coordination Platonic polyhedra.
摘要
本文介绍了两个直接的铂（1 和 6a/b）和三个乙炔基-铂苝衍生物（2、8 和 9）的合成和表征，它们分别具有 2、4 或 5 个平面四方铂中心。碗状取代基的结构与苝保持可比，通过 VT NMR 评估的碗反转的动态行为支持了在溶液中存在持久的碗状结构。这些铂-苝是未来组装配位柏拉图多面体的良好结构构筑基元。
