  2. 1. 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.

  4. 2. Singlet Fission and Exciton Coupling Design Principles for Efficient Photon Harvesting

    Author : Rasmus Ringström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; exciton coupling; electron transfer; Singlet fission; transient absorption spectroscopy;

    Abstract : Extensive research efforts have been dedicated to unravelling the diverse array of processes triggered by the interaction of light with matter. Harnessing and comprehending some of these phenomena holds immense potential in humanity's transition towards renewable energy sources. READ MORE

  5. 3. Excited state dynamics in the strong coupling regime

    Author : Jürgen Mony; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Strong exciton-photon coupling; Excited state dynamics; light-matter interactions; photoswitch; aggregated states;

    Abstract : Strong exciton-photon coupling exhibits the possibility to modify photophysical and photochemical properties of organic molecules without changing their structure. This is due to the formation of hybrid light-matter states, called polaritons, which are created when the strong coupling regime is achieved. READ MORE

  6. 4. Exciton coupling and energy transfer in perylene-based systems

    Author : Alexei Cravcenco; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic Chemistry; Photophysics; Energy transfer; FRET; Perylene; J-aggregate;

    Abstract : Understanding the nature of photoinduced processes in organic molecules is essential for the design and synthesis of compounds with desired photochemical properties. This dissertation aims for gaining knowledge and mechanistic understanding of energy transfer in perylene-based systems. READ MORE

  7. 5. Microscopic Modeling of Exciton-Polaritons in Two-Dimensional Materials

    Author : Beatriz Ferreira; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; exciton-polaritons; 2D materials; diffusion; absorption;

    Abstract : Integrating 2D materials into high-quality optical microcavities opens the door to fascinating many-particle phenomena including the formation of exciton-polaritons. These are hybrid quasi-particles inheriting properties of both the constituent photons and excitons. READ MORE
