采用金属离子为模板合成了一类由无金属或金属卟啉修饰的冠醚大分子环,并通过1H NMR、MS、紫外、荧光等方法对其进行了结构表征和性能测试。采用具有4,4’-联吡啶的客体分子与冠醚环进行组装,以荧光滴定法测定了主客体分子间的结合常数。结果表明,这种冠醚环不仅具有卟啉优异的光电性质而且能与客体分子形成了1∶1的类轮烷体系。 A series of crown ether macromolecule rings modified by metal-free or metalloporphyrin were synthesized using metal ions as templates. Their structures and properties were characterized by 1H NMR, MS, UV and fluorescence spectroscopy. The guest molecules with 4,4’-dipyridyl were assembled with the crown ether ring, and the binding constants between host and guest molecules were determined by fluorescence titration. The results showed that the crown ether ring not only possesses the excellent photoelectric properties of porphyrin, but also forms a 1: 1 rotaxane system with guest molecules.
