A new publication just appeared in Angewandte Chemie International Edition , in collaboration with IPCMS, Strasbourg, and University of Heidelberg. We studied the self-assembly of a conjugated polymer under vibrational strong coupling. It appeared under electron microcopy that the supramolecular morphology is totally different from that observed in the absence of strong coupling. Morever the self-assembly kinetics is modified and depends on which bond of the solvent is coupled.
