Guanosine and its derivatives have a high potential for self-recognition and self-assembly, as well as the recognition ability for other biologically important molecules. This book explores in detail these properties with the goal of increasing knowledge of the basic principles of guanosine-assembly, synthesis of new optimised materials and exploration of their electronic and optical properties. Following the work of COST Action MP0802, the aim is to design novel reproducible and well ordered supramolecular structures to serve as molecular-scale architectures for new hybrid molecular electronics. Coverage includes synthesis, characterisation and optimisation, theoretical modelling and prediction, biochemical and biorecognition properties and applications in nanotechnology especially in molecular electronics. Appealing to researchers working in the field ranging from chemists, biologists and material scientists, this title will be a welcome addition to the inter-disciplinary literature providing direction for future research and ideas for industrial applications.
