Simple Coordination Complexes of Cucurbit[n]urils with Metal Ions - Supramolecular Assemblies of Cucurbit[n]urils with Metal Ions - page 33

two portal carbonyl oxygens of the Q[10] molecule. As mentioned previously, we
recently reported the new largest member of the Q[ n ] family, namely tQ[14]. In
fact, determination of the structural characteristics of tQ[14] was also first based
on the determination of the complex of tQ[14] molecules with the aid of Eu 3 + cat-
ions (Fig. 2.26 b) [ 5 ]. This was accomplished because the tQ[14]/Eu 3 + structures
belong to coordination polymers, which will be presented in detail later.
Based on the above results, we summarized the main simple Q[ n ]-based com-
plexes, in which Q[ n ]s play the role of poly-dentate ligands and interact with
metals through direct coordination to the portal carbonyl oxygens. These simple
complexes could be applied to selective inclusion of anions, absorption of mol-
ecules, drug delivery, and so forth.
