a Transient absorption data of [G4]-P48 spanning nanosecond to microsecond time scales along with b kinetic cuts at 530 nm near the peak of the triplet excited state absorption feature. These data show a long-lived triplet pair and triplet exciton population whose average behavior can be characterized using two first-order time constants spanning 100–250 ns and 21–27 μs. In both cases, the time constants become shorter for higher generations.
