A fast growing area within soft materials is organic semiconductors that have electronic properties similar to silicon. They are being investigated for application in flat panel displays and lighting, plastic electronics, and solar cells. A world-leading initiative in the field of organic semiconductors, this programme will focus on development of new materials and a fundamental understanding of how they work in opto-electronic devices. The programme will explore dendritic materials that enable precise control over the intermolecular interactions that are key to the success of using organic semiconductors, with the results having broad implications for all types of organic semiconducting materials.
