4.1 Introduction

This chapter deals mainly with the research carried out in our
laboratory over the last 15 years on the supramolecular organization
of lipophilic guanosine derivatives (LGs) and its implementation as
a tool for obtaining functional materials. Of course, several other
groups have been active in the field and the reader is invited to refer
to recent reviews [1] for a broader coverage of the subject.
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 (N
