a Transient absorption spectrum for various samples, including pure PITIC-ThF Pdot, b PITIC-ThF Pdot with 3 wt% Pt, and c PITIC-ThF Pdot with 0.1 M AA and 3 wt% Pt, at different time delays after excitation at 650 nm with a power of 0.9 µW. d The decay dynamics of the transient absorption were compared for neat PITIC-ThF Pdot, PITIC-ThF Pdot + Pt, and PITIC-ThF Pdot + AA + Pt, when excited at 650 nm and probed at 959 nm, which were assigned to PITIC-ThF Pdot exciton decay.
