Figure 4. Cellular uptake of dipyridophenazine (dppz) complexes of Ru(II).

Figure 4

The lipophilic complex [Ru(DIP)2dppz]2+ is observed inside HeLa cells at lower incubation concentrations and shorter times (top, 5 µM for 2 h) than [Ru(bpy)2dppz]2+ (bottom, 20 µM for 72 h). Structures of complexes are shown at left. Scale bars are 10 µm.
