Intriguing molecular discoveries in display materials

It is a widely-accepted scientific fact that the motions of molecules increase as their temperature rises. However, we have recently made a counterintuitive discovery in an organic semiconductor called ‘CADN’. Within a thin film of this material, our team has found that the motion of one part of the CADN molecule increases, while another part becomes more ordered as the temperature increases and approaches the material’s phase transition. This research is scientifically intriguing, but also has profound implications for improving display technologies based on organic semiconductor materials.
