A rigid organic ligand, formed through the subcomponent self-assembly of p-toluidine and 6,6'-diformyl-3,3'-bipyridine, was employed in a systematic investigation into the synergistic and competing effects of metal and anion templation. A range of discrete and polymeric metal-organic complexes were formed, many of which represent structure types that have not previously been observed and whose formation would not be predicted on taking into account solely geometric considerations. These complex structures, capable of binding multiple guests within individual binding pockets, were characterized by NMR, ESI-MS, and single-crystal X-ray diffraction. The factors that stabilize individual complexes and lead to the formation of one over another are discussed.
采用刚性有机配体,由对甲苯胺和 6,6'-二醛基-3,3'-联吡啶的亚组分自组装形成,对金属和阴离子模板的协同和竞争效应进行了系统研究。形成了一系列离散的和聚合的金属有机配合物,其中许多代表以前没有观察到的结构类型,并且仅考虑几何因素的话,其形成是无法预测的。这些具有在单个结合口袋内结合多个客体能力的复杂结构通过 NMR、ESI-MS 和单晶 X 射线衍射进行了表征。讨论了稳定单个配合物并导致形成另一个配合物的因素。
