Abstract

Coordination-driven self-assembly of organometallic η6-arene ruthenium(II) supramolecular architectures (MA1–MA4) was carried out by employing dinuclear ruthenium acceptors [Ru2(μ-η4-C2O4)(CH3OH)26-p-cymene)2](CF3SO3)2 (Rua), [Ru2(μ-η4-C6H2O4)(CH3OH)26-p-cymene)2](CF3SO3)2 (Rub), [Ru2(dhnq)(H2O)26-p-cymene)2](CF3SO3)2 (Ruc) and [Ru2(dhtq)(H2O)26-p-cymene)2](CF3SO3)2 (Rud) separately with a new tetratopic donor (TD) in methanol at room temperature [TD = N,N,N′,N′-tetra(pyridin-4-yl)-[1,1′-biphenyl]-4,4′-diamine]. All the coordination architectures were characterized by using spectroscopic techniques. The potency of these self-assembled architectures against human cervical cancer HeLa and human lung adenocarcinoma A549 cell lines is explored in vitro using MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide), annexin V-FITC/PI and 2′,7′-dichlorofluorescein-diacetate assays.
