Résumé

We report on the spin state photoswitching dynamics triggered by a femtosecond laser of [(TPA)FeIII(TCC)]+ cations in a new salt with SbF6- 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 PF6- 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 SbF6- salt, as its thermal crossover occurs at higher temperature.
