Out-of-Equilibrium Dynamics of a Grid-Like Fe(II) Spin Crossover Dimer Triggered by a Two-Photon Excitation

Abstract

The application of two-photon excitation (TPE) in the study of light-responsive materials holds immense potential due to its deeper penetration and reduced photodamage. Despite these benefits, TPE has been underutilised in the investigation of the photoinduced spin crossover (SCO) phenomenon. Here, we employ TPE to delve into the out-of-equilibrium dynamics of a SCO Fe
