Spin‐State Photoswitching Dynamics of the [(TPA)Fe(TCC)]SbF 6 Complex

We report on the spin state photoswitching dynamics triggered by a femtosecond laser of [(TPA)Fe III (TCC)] + cations in a new salt with SbF 6 – anions. Femtosecond optical pump‐probe spectroscopy and picosecond X‐ray diffraction techniques were combined to investigate the different steps of the out...

Description
Summary:We report on the spin state photoswitching dynamics triggered by a femtosecond laser of [(TPA)Fe III (TCC)] + cations in a new salt with SbF 6 – anions. Femtosecond optical pump‐probe spectroscopy and picosecond X‐ray diffraction techniques were combined to investigate the different steps of the out‐of‐equilibrium dynamics. The obtained results are very consistent with the ones previously reported for the PF 6 – salts. If the ultra‐fast responses of the cations in both salts are similar, the spin conversion due to laser heating is slightly shifted to higher temperature in the SbF 6 – salt, as its thermal crossover occurs at higher temperature.
