A new series of dinuclearruthenium(II) polypyridyl complexes, which possess larger pi-conjugated systems, good water solubility and pH resistance, and high photostability, were developed to act as single and two-photon luminescence cellular imaging probes.
Mitochondrial dynamic processes are essential for mammalian development and are engaged in several diseases. However, commercial mitochondrial probes are currently too limited to satisfactorily track these dynamics. In this present work, seven dinuclear iridium(III) complexes [(ppy)2Ir(L1–7)Ir(ppy)2]2+ (Ir1–Ir7, ppy = 2-phenylpyridine, L = 1,3-bis(1-substituted-imidazo[4,5-f][1,10]phenanthroline-2-yl)benzene)
