Exciton Localization on Ru-based Photosensitizers Induced by Binding to Lipid Membranes [PDF]
J. Phys. Chem. Lett. 2018, 9, 4, 683-688, 2020 The characterization of electronic properties of metal complexes embedded in membrane environments is of paramount importance to develop efficient photosensitizers in optogenetic applications. Molecular dynamics and QM/MM simulations together with quantitative wavefunction analysis reveal an unforeseen difference between the exciton formed upon ...
