Conjugated polymers posses many exceptional electronic, optical and thermal properties and thus are well suited for organic semiconducting applications, such as solar cells and light emitting diodes. Among conjugated polymers polybenzobisazoles posses many exceptional electronic, optical and thermal properties and thus are ideally suited for diverse organic semiconducting application. Yet these materials have found limited utility due their lack of solubility in organic solvents. Unfortunately, the harsh conditions required for the synthesis of benzobisazoles has prevented the synthesis of benzobisazoles bearing reactive handles. Recently we have developed a mild approach for the synthesis of benzobisoxazoles resulting in several building blocks suitable for designing new polymers. The utility of these compounds for the synthesis of novel, solution processable polybenzobisazoles and the electronic and physical properties of these polymers will be presented.
