1D dynamical studies in the gas-phase, solution-phase and thin-films

Task 22 1D dynamics studies will capture in real time the evolving dynamics and photoprotection mechanisms operating in these molecules on an ultrafast timescale Gasphase femtosecond laser spectroscopic studies will unravel the photon conversion dynamics of accessible excited states of isolated SMsDPPsPhyCs and oligomers UW Solutionphase studies using femtosecond transient electronic and transient vibrational absorption spectroscopy will investigate in detail how the solvent influences the evolution of the excited state and the quantum yield for heat generation UB UW Thinfilm TF studies on SMDPPPhyC solutions sprayed onto thin transparent membranes will mimic as close to realistic conditions as possible We will then repeat the protocol used for the solutionphase studies to investigate how the excited state dynamics are affected by incorporating the molecules on a thinfilm UB UW but also employ UV pumpTHz probe studies to elucidate how the solid interface perturbs both the excited and ground state dynamics UW
