摘要

Abstract: Five new dicopper (1) knots have been synthesized as well as their face-to-face isomers. The knots range from 80-to 90-membered rings, and their preparation yields depend crucially on structural parameters such as number of methylene fragments linking the two chelating units and length of the poly (ethy1eneoxy) unit used in the cyclization reaction. The best yield was obtained for an 84-membered knotted ring with a-(CH2) 6- ...
