Résumé

We present a systematic study of the ultrafast fluorescence with broadband detection and ∼110 fs resolution of 5,10,15,20-tetraphenylporphin (TPP) and 2,3,7,8,12,13,17,18-octaethylporphin (OEP), with open 3d-shell metals. We also revisit the cases of the closed-shell ZnTPP and ZnOEP systems. We find that in all cases, the relaxation from the Soret (B)-state to the Q-states (S
