These colocalization experiments offer new insight into the interactions between HeLa cells and g-Odots, namely that there is moderate-to-high positive colocalization between the emission from g-Odots' and from LysoTracker Blue (a commercially available lysosome-targeting fluorophore). To the best of our knowledge, this is the first time the localization of g-Odots within cells has been studied and this is also the first report of MR-TADF emitters being used as bioimaging probes. These findings may help guide future cellular imaging with these materials.
