From: Parallel triplet formation pathways in a singlet fission material
a TA spectra of HR-TDPP-TEG in THF after photoexcitation at 2.3 eV with 35.4 μJ/cm2 at room temperature. Steady-state absorption (gray solid line) and PL (gray dashed line) are presented for reference. b averaged TA kinetics (open symbols) in the two spectral regions (blue—SE region, red—PIA region). The black solid lines are the best global fit of the two kinetics with a triexponential function.
