Talk given by Dr. Jino George ISIS Universite de Strasbourg Strasbourg, France Abstract: Strong light-matter interaction has much potential for modifying the chemical and physical properties of molecular materials. [1] Recently we have shown for the first time that molecular vibrational transitions can be coherently coupled to vacuum states in the infrared region. [2] Inspired from the previous work on excited state chemical reactivity[1a] we strongly coupled molecular liquid in a micro-fluidic system, a first step in that direction to control the kinetics and thermodynamics of a given chemical reaction under the vibrational strong coupling (VSC) conditions. [3] Very recently, we experimentally proved this to be true by controlling a ground state de-protection reaction of an alkynyl silane molecule under VSC of the C-Si stretching mode. [4] We have also managed to achieve ultra-strong vibrational coupling (Rabi splitting ˃25 % of the fundamental transition energy of a vibrational band) in molecular liquids, which should have important consequence on their reactivity energy landscape. [5] After introducing our recent observations on chemical reactivity under strong coupling, effort will be made to discuss the future perspective of this new emerging area of molecular science.
