    • As a fast repetition rate of theexcitation pulse (5 kHz, 200 μs delay between the pulses) was used, there is a possibility that the observed TPA values would have been artificially augmented by the contribution from the triplet-triplet excited-state absorption (ESA). However, it is expected that, considering the lifetime of the lowest triplet state lifetime of the similar molecules (< 200 μs), the triplet state may be depopulated before ESA by a subsequent pulse. Hence, the TPA augmentation by ESA will be very minimal or negligible and does not affect the general trend observed for these molecules.
