Furthermore, two different sized 3-D supramolecular cages are formed upon mixing one ditopic organoplatinum acceptor and two different sized tritopic donors from the self-sorting process. The formation of these polygons and cages is characterized using NMR spectroscopy and electrospray ionization mass spectrometry (ESI-MS). In all cases, the self-sorting process is directed by the size of the donor building
提出了二维 (2-D) 多边形和三维 (3-D) 笼的协调驱动自组装中的尺寸选择性自分类。两种不同大小的多边形(矩形和三角形)是从分子“夹子”或 60 度有机铂受体与不同长度的联吡啶连接体的混合物中自发形成的。此外,两个不同尺寸的 3-D 超分子笼在混合一个双位有机铂受体和来自自分选过程的两个不同大小的三位供体后形成。这些多边形和笼子的形成使用核磁共振光谱和电喷雾电离质谱 (ESI-MS) 进行表征。在所有情况下,自分类过程都由捐赠者构建块的大小和动态的、
