A cyanine dye with R 2 = -OH group has been recently reported to exhibit simultaneous selectivity toward cellular nucleus and mitochondria. In order to investigate the role of the substituents towards the organelle selectivity, probe 2 (with R2 = -OR group) was synthesized in good yields. When applied to cellular study, probe 2 exhibited excellent selectivity to stain mitochondria of live cells without observing nucleus staining. The study indicated that the R2 group was the key component in tuning the observed
