We also quantify the SF rate constant and the upper bound of the ISC rate constant in TIPS-Tn, and show that ISC is potentially faster, and even more important to consider for this molecule than for TIPS-Pn. We additionally note that excimer formation is not observed in dilute solutions of TIPS-Tn, even when SF is observed, and therefore suggest that previously observed excimer formation may be due to aggregate formation in concentrated solutions.
