ABSTRACT
This chapter is organized in two main parts. In the first part the supramolecular architectures originated by LGs, both in the absence and in the presence of metal cations, will be described. The second part will deal with the use of these structures for obtaining functional materials or devices.Among nucleobases, guanine (G) (Fig. 4.1) is the most interesting and versatile one, as the presence of different donor (N1H and N2H)
and acceptor sites (O6, N3 and N7) located in a self-complementary arrangement coupled with a polarized aromatic surface makes it a unit able to easily self-assemble by both multiple hydrogen bonding and π-π stacking.
