In chapter 1, after covering briefly the tools currently used to investigate the nano world, we explore the chemistry of acetylenes applied in coupling reactions to form phenyl-acetylene bonds. We then turn our attention to supramolecular chemistry as a driver for the formation of self-assembled networks, allowing for a bottom-up approach to achieve nanopatterned, functional surfaces.
In chapter 2, the concept of phenyl-acetylene building blocks is presented. This modular approach to the assembly nano scale architectures makes the ‘mass production’ of a library of interesting building materials viable through organic synthesis. Both aryl and carbazole building blocks are explored, with a focus on their scope for further assembly to larger architectures.
Chapter 3 discusses applications of the building block approach to molecular electronics. Computing devices could become much faster, smaller, and cheaper to run if we move away from the silicon-based transistor towards functional single molecules. We have synthesised a series of linear, fully conjugated nano-rods and stars to act as molecular wires in an attempt to fabricate the first functional three-terminal device.
In chapter 4 we investigate the synthetic route towards an organic metamaterial. The building block methodology is applied an refined in the 26 step synthesis of a giant, fully conjugated carbazole based macrocyle.
Finally, in Chapter 5 we look to the synthesis and STM investigations of a family of star-shaped molecular rods demonstrating an unprecedented level of control of single molecular organisation in an extended array.
