An interesting dimension of metal-coordinated self-assembly that is often ignored, or at least not exploited to its fullest extent, occurs when the resulting coordination complex is a charged species and, as such, in need of a counterion. This counterion itself presents yet another subtle instance of ionic self-assembly, which often is overshadowed by its partner, the coordination complex. The second multi-functional side-chain supramolecular polymer system is based on this simple but important concept [14, 106-111]. In 2003, Ikkala and coworkers reported a study in which they exploited (1) a side-chain functionalized polymer, poly(vinyl-pyridine), (2) metal-coordination self-assembly via a tridentate Zn2+ complex and (3) ionic self-assembly through functionalized counterions, i.e. dodecylbenzene-sulfonate ions, to form multiple self-assembled complexes which adopted a cylindrical morphology (Fig. 7.23) [112].

Gold(I) generally exhibits two-coordinate linear geometry and is thus a good candidate for the formation of low-coordinate self-assembled structures. However, aurophilic Au-Au interactions often play an important role in structure determination and stabilization. ...

Five bis-calecholate ligand syntones (Scheme 4.119) have been used [116] to evaluate combinatorial libraries of their coordination self-assemblies with metal ions as hosts for various guests. As follows from ESI-MS and NMR data, the dynamic combinatory library with many assemblies simultaneously being present in a solution is made from labile ligand syntones and...
