A different approach: highly encapsulating macrocycles being used as organic tectons in the building of CPs

Abstract : For the first time, an azamacrocycle has been used to build Pb(II) 1D coordination polymers. Cross-bridged cyclam H2cb-teapa, that has a strong proton sponge behaviour, adopts a zwitterionic form and therefore acts as the external bridge rather than coordinating Pb(II) in an endocyclic way. The resulting 1D coordination polymer of formula {[Pb(Cl)(H2cb-teapa)]ClO4}n has been analysed by single crystal X-ray diffraction. Interestingly, the polymer adopts a singular tube-like structure, which results from the alternation of the  and  enantiomers generated by the layout of the arms of the organic linker.
