Summary on Grant Application Form
Conjugated organic molecules and polymers possess the electronic properties of inorganic semiconductors and metals, while being of lower cost, lighter weight and more amenable to device manufacture. Furthermore, these properties can be readily controlled by manipulation of the molecular or macromolecular structure, which offers a distinct advantage over many comparable inorganic materials. As a result, organic replicas have now found applications as wires, light-emitting diodes, sensors, field-effect transistors, photovoltaic devices and lasers.The optimisation of many such devices, however, relies on either balancing charge carrier transport or manipulating the diffusion of excitons, both of which require control over the supramolecular structure. Unfortunately, the patterning of conjugated organic units into nanoscale objects of predetermined size and shape remains a fundamental challenge. This problem is further amplified by the need for more complex architectures, such as junctions or compartmentalised structures and composites, for the extensive realisation of nanoscale organic replicas of inorganic microelectronic components. In this collaborative proposal we target proof of concept studies that will permit the development of a new platform for the creation of functional 1-D semiconducting nanostructures based on block copolymers with crystalline, pi-conjugated polythiophene segments. This offers the simplicity of solution phase self-assembly but affords potential control over the dimensions of the structure. Furthermore, this new method also offers exciting possibilities for accessing both compartmentalised and hybrid structures, which should function as key components in a variety of nanoscale devices.
