Based on the affinity of CB towards alkyl diammonium ions, stable polyrotaxanes with high structural regularities in solid state were synthesized using the principles of self-assembly and coordination chemistry . In this way, by threading CB molecules with N,N ' -bis (4pyridylmethyl)-1,4-diaminobutane dihydrochloride and reaction with Cu(NO3)2, the construction of a polyrotaxane coordination polymer was achieved. Likewise, the aliphatic diamines complexes with CB were used for the synthesis of rotaxanes and polyrotaxanes characterized by high stability . Moreover, CB binds spermine yielding highly stable 1:1 host-guest complexes that allow the synthesis of rotaxane and pseudorotaxane and also form a 2:1:1 complex with a crown ether and spermine in solution . By using DFT calculations, the members of the CB family and CB -spermine host-guest complexes were investigated with respect to geometries, stabilities, electronic properties and NMR-shielding . The results obtained highlight that all molecules studied are highly symmetrical, show geometric flexibility and a characteristic partial charge distribution for their complex building. The CB -spermine complex could be characterized as a very stable and symmetric combination. In the same area of research, another compound studied was 11-aminoundecanoic acid which is able to form mixed complexes with one molecule of α-cyclodextrin or β-cyclodextrin and one molecule of CB . It was reported that the complexes of CB , α-cyclodextrin, and β-cyclodextrin with 11-aminoundecanoic acid were employed as building blocks to construct polymers . The studies on the complexes of amines with CB demonstrated that these complexes can be used as building blocks for the synthesis of polymers, polyelectrolyte layer assemblies and metal-organic networks .
