In order to improve the template synthesis of our first molecularknot, we examined slightly modified systems and we now report the synthesis of four new dicopper (I) trefoilknots with a ring size ranging from 80 to 90 atoms.

Five new dicopper(I) 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(ethyleneoxy) unit used in the cyclization reaction. The best yield was obtained for an 84-membered knotted
