Chain length determines molecular colour
Researchers at ETH Zurich have developed fluorescent polymers whose colour can be easily tuned. Depending on their length, the polymers emit a different colour. Potential applications include biomedicine, security printing and solar energy.

Around the world, a huge amount of research and development work is currently being done on carbon-containing, or organic, molecules that emit coloured light after appropriate excitation. This research field is driven by the display industry and the development of biomedical imaging techniques. While precise colour tuning in organic fluorescent dyes has so far usually been achieved by mixing different molecules, ETH researchers have now developed an approach that can generate a broad palette of colours by way of che ....
