The combination of a disulfonated-dibenzo-24crown-8 ether wheel and a dicationic 1,2-bis(pyridinium)ethane axle yields a neutral [2]pseudorotaxane which in combination with neutral metallic units such as a Cu(II)benzoate paddlewheel or Cu(I)Br unit yields one-dimensional coordination polymers (linear and bent) which are the first examples of charge neutral, metalâorganic rotaxane frameworks.
