Femtosecond Spin‐State Photoswitching of Molecular Nanocrystals Evidenced by Optical Spectroscopy

Abstract

Quick change: Femtosecond optical pump–probe spectroscopy is used to study the photoswitching dynamics of FeIII spin-crossover nanocrystals. Results indicate that up to 10 % of the molecules can be photoswitched from low-spin to high-spin states within less than one picosecond.
