BIO

Dr. Simon holds a Bachelor’s and Master’s degree from the Ecole Nationale Supérieure de Chimie de Montpellier (France). He then moved to New England and started a Ph.D. in Polymer Science and Engineering from the University of Massachusetts, Amherst under the guidance of Prof. E. Bryan Coughlin working on hybrid organic/inorganic materials. In 2008, Yoan then moved back to Europe where he was awarded an ETH Fellowship to work on two-dimensional polymers under the supervision of Prof. A. Dieter Schlüter at the Swiss Polytechnic Institute of Technology in Zürich. After a year, he took on a position as junior Faculty (maître-assistant) at the then newly founded Adolphe Merkle Institute (headed by Prof. Christoph Weder) at the University of Fribourg, Switzerland where he stayed for six year developing new research avenues in the field of optically and mechanically active polymeric materials. Since January 2016, Yoan has joined the School of Polymers and High Performance Materials at the University of Southern Mississippi as an Assistant Professor.

ABSTRACT

Light upconversion (UC) by means of triplet-triplet annihilation (TTA) is an interesting photophysical process that is promising for a whole host of applications ranging from solar harvesting to imaging. While this phenomenon was discovered over 50 years ago in solution, its development in solids is more recent. TTA-UC is predicated on the use of chromophore pairs with finely tuned electronic levels. This contribution will give an overview of our latest achievements in the field for the development of polymeric materials facilitating efficient TTA-UC. A few systems will be discussed including rubbery and glassy polymer blends and copolymers with suitable chromophore pairs, upconverting (nano)particles, gels, and nanostructured materials. The data exposed will serve to depict the structure-property relationships of upconverting polymeric materials and outline global design principles.
