Abstract

A novel [3]rotaxane composed of two 25-membered crownophanes and one axle molecule having two anthryl end groups was successfully synthesized via covalent bond formation followed by aminolysis, and can incorporate caesium ion into the space between the two macrocycles as a 1 ∶ 1 sandwich-type complex, whereas it makes a 1 ∶ 2 complex with lithium ion.
