Fig. 10: Transient absorption spectroscopy in dichloromethane.

Transient absorption spectra recorded for 1 (a) and 2 (c) in dichloromethane upon pumping at 400 nm at different delay times. Kinetic traces of 1 (Inset in a) and 2 (Inset in c) at selected wavelength. Decay-associated spectra and corresponding time constants of 1 (b) and 2 (d) derived from a global multiexponential fit applied on the transient absorption data (c).
