Supramolecular architectures generated by self-assembly of guanosine derivatives

Abstract

Nature's use of a simple genetic code to enable life's complex functions is an inspiration for supramolecular chemistry. DNA nucleobases carry the key information utilizing a variety of cooperative and non-covalent interactions such as hydrophobic, van der Waals, pi-pi stacking, ion-dipole and hydrogen bonding. This tutorial review describes some recent advances in the form and function provided by self-assembly of guanine (G) based systems. We attempt to make connections between the structures of the assemblies and their properties. The review begins with a brief historical context of G self-assembly in water and then describes studies on lipophilic guanosine analogs in organic solvents. The article also focuses on examples of how G analogs have been used as building blocks for functional applications in supramolecular chemistry, material science and nanotechnology.
