About the Research
Development of functional materials from aliphatic polyketones as 'carbonyl ropes'
Since function is largely determined by shape, my goal is to create molecules that can be shaped with ease. Inspired by clay ropes used in pottery, I employ mainly polyketone polymers of determinable lengths whose flexible nature allows for the creation of any imaginable molecular shape. In addition, the great wealth of knowledge on carbonyl group reactions that can act on these polyketones enables us to introduce many desirable modifications into our “molecular ropes”.
ICReDD is a wonderful opportunity to find applications for these molecules, and to predict useful shapes and modifications, through the collaboration with information scientists and computational chemists.
The Researcher’s Perspective
Watching people grow to become better and better than myself is a source of much fun to me. Therefore, I encourage my students to discuss and think for themselves, and doing science is a tool for that. But if that personal growth can also result in new materials or new chemical reactions, that’s even better!
