Supramolecular chemistry investigates chemicals systems and large architectures build from simple molecular components connected via weak, non-covalent and reversible interactions. The same holds for molecular chemistry when the molecular entity contains covalent bonds that may form and break reversibility, so as to allow a continuous modification in constitution by reorganization and exchange of building blocks. These features define a Dynamic Combinatorial Chemistry (DCC) on both the molecular and supramolecular levels. The field of DCC is currently undergoing a revival, largely on account of our increased understanding of supramolecular phenomena and the subsequent development of self-assembly processes.

The results obtained so far show the huge potential of complex and functional chemical systems generated by implementation of supramolecular and DCC approach, however the full understanding of controlled synthesis of multicomponent molecular and supramolecular architectures (2D and 3D), with predicted physico-chemical parameters was not yet achieved.

Taking into account the big potential of supramolecular and dynamic covalent chemistries in the creation of functional architectures we decided to investigate the formation of complex chemical systems by means of dynamic/reversible covalent and non-covalent bonds. The purpose of our studies is the development of new complex supramolecular and molecular dynamic systems of different topologies and functions. The influence of the employed dynamic bonds on the structural, physico-chemical and functional properties of the synthesized architectures is of our main interest.
