A series of neutral, platinum-based macrocycles was synthesized from rigid oxygen donor building blocks via self-assembly. The combination of a platinum-based 60 degrees acceptor unit 1 with several linear and angular dicarboxylate bridging ligands afforded hitherto unknown neutral platinum-based supramolecular triangles and rhomboids. In addition, a similar reaction of the diplatinum molecular clip 6 and three different linear dicarboxylates led to the formation of neutral molecular rectangles. Most of the macrocycles were characterized by X-ray single-crystal structure analysis, and, in all cases, NMR spectra were consistent with the formation of single highly symmetrical species.
通过自组装，由刚性氧供体构建单元合成了一系列中性铂基大环化合物。铂基60度受体单元1与几种线性和角形二羧酸桥联配体的组合产生了迄今未知的中性铂基超分子三角形和菱形。此外，双铂分子夹6与三种不同的线性二羧酸酯的类似反应导致形成中性分子矩形。大多数大环化合物通过X射线单晶结构分析进行了表征，并且在所有情况下，核磁共振光谱与单一高度对称物种的形成一致。
