  7. 5. Strong exciton-photon and exciton-exciton coupling and its effects on molecular photophysics

    Author : Yi Yu; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Strong coupling; triplet transition dynamics; TADFs; aggregate states;

    Abstract : The energy of molecular states and their transition dynamics form the key properties to understand the photophysics of organic molecules. Strong exciton-photon and exciton-exciton couplings enable the possibility to manipulate these properties without changing the chemical structures. This is due to the formation of new energy states.
