The design and synthesis of supramolecular architectures with parallel control over shape and dimensions is a challenging task in current organic chemistry [13, 14], The information stored at a molecular level plays a key role in the process of self-assembly. Recent examples of nanoscopic supramolecular complexes from outside the dendrimer held include hydrogen-bonded rosettes [15,16], polymers [17], sandwiches [18, 19] and other complexes [20-22], helicates [23], grids [24], mushrooms [25], capsules [26] and spheres [27].

Quantum-field chemistry concept [5-9] treat transport of molecules inside the condensed phases of water as conduction through emptiness of two kinds (see Fig. 2). It is intramolecular emptiness restricted by grid intramolecular hydrogen (O-H—O) a-bonds inside supermolecule and, secondly, it is supramolecular emptiness lying between supermolecules confined by network of supramolecular hydrogen (O-H... O) (S-bonds and electrostatic y-bonds. 

Evolution of a constitutional dynamic library of dynamer strands may be driven by metal ion binding towards the generation of a specific metallo-supramolecular architecture, such as a [2x2] grid [54], or of a dynamer presenting specific interactions and properties (such as optical self-sensing) [57] (see also Figs. 7 and 8 in [9]).
