In the search for new fluorescent triphenylamine (TP) derivatives, we studied the influence of the position and substitution of diverse heterocyclic substituents. A library of 10 fluorescent triphenylamines bearing either oxazoles or thiazoles and pyridiniums, substituted at different positions has been developed. The approach is based on a convergent C?H activation reaction between pyridine-oxazoles or pyridine-thiazoles and di-iodo triphenylamine. We showed that the nature and substitution pattern of the 5-membered- (oxazole, thiazole) or 6-membered heterocycle (pyridine) has a strong influence on their fluorescence properties and on their localization in living cells as they stain either the nucleus or mitochondria.
