Science Daily August 30, 2023 Photoswitches are molecular systems that are chemically transformed after interaction with light and they find potential application in many new technologies. The design and discovery of photoswitch candidates require intricate molecular engineering of a range of properties to optimize a candidate to a specific application. An international team of researchers (Denmark, Spain) performed a large-scale screening of approximately half a million bicyclic diene photoswitches in the context of molecular solar thermal energy storage using ab initio quantum chemical methods. They devised an efficient strategy for scoring the systems based on their predicted solar energy conversion […]

New breakthrough shows how short pulses of light destroy particles
Phys.org July 6, 2023 Molecular polaritons are hybrid light-matter states that emerge when a molecular transition strongly interacts with photons in a resonator. At optical frequencies, this interaction unlocks a way to explore and control new chemical phenomena at the nanoscale. However achieving such control at ultrafast timescales is challenging as it requires a deep understanding of the dynamics of the collectively coupled molecular excitation and the light modes. An international team of researchers (Germany, Italy, Sweden, Spain, Luxembourg) investigated the dynamics of collective polariton states, realized by coupling molecular photoswitches to optically anisotropic plasmonic nanoantennas. Pump-probe experiments revealed an […]
