From: Femtosecond-Resolved Excited State Relaxation Dynamics of Copper (II) Tetraphenylporphyrin (CuTPP) After Soret Band Excitation

Figure 3

TA spectra of CuTPP in pyridine (a,b) and piperidine (c,d). (a,c) Contour plot of experimental data, (b,d) Kinetic traces recorded at 480 nm represented to triplet state relaxation. Ultrafast component observed in piperidine with time constant of 300 fs (inset in (d)) reflected the intrinsic lifetime of CuTPP-piperidine exciplex (see the text).
