Designing Materials for High-Tech Applications

Since their discovery almost 40 years ago conjugated polymers have been of tremendous scientific and technological interest due to their semiconductor properties. As a result they are well suited for organic use in applications, such as solar cells and light emitting diodes. Unfortunately, there are several issues that have to be addressed before real-life commercialized products based on these materials can be developed. Since the properties of organic semiconductors can be readily modified through chemical synthesis, we have turned our attention towards the design and synthesis of novel building blocks. Our system of choice, polybenzobisazoles posses many exceptional electronic, optical and thermal properties and thus are ideally suited for diverse organic semiconducting applications. However, these materials have found limited utility due their lack of solubility in organic solvents and the harsh conditions required for their synthesis. Using theoretical models, our group designed a series tunable materials, our recent developments in this area will be presented.
