solution and pKa values were determined in both water and MeCN. Taking advantage of these acidic NH protons, anion sensing behavior of the complex was thoroughly investigated in both acetonitrile and water through multiple optical channels. The complex behaves as sensor for F−, CN−, AcO- and H2PO4- in acetonitrile without much selectivity, while selectivity dramatically increases in water where it exclusively

calculations. The DNA photocleavage and singlet oxygengeneration properties as well as in vitro anticancer activities against five cancer cell lines are studied as well. The results demonstrated that pH-induced luminescence switching, DNA binding, and anticancer properties of 1 are much improved with respect to those of the mononuclear analog [Ru(bpy)2(Htip)]Cl2 Htip = 2-(thiophen-2-yl)-1H-imidazo[4

Two dinuclearRu(II) polypyridyl complexes functionalized with vacant coordination sites have been designed and synthesized. Their photophysical properties and interactions with various metal ions have been investigated at room temperature. The two complexes exhibit different UV/Vis absorption and emission intensities. When titrated with various metal ions, complex [Ru(bpy)2}2(μ2-L(1))](4+) exhibits

Compositions of the invention include metal-based coordination complexes, which are preferably tunable photodynamic compounds. The compositions and complexes are useful as therapeutic agents and as in vivo diagnostic agents for treating or preventing diseases including those that involve hyperproliferating cells in their etiology, such as cancer. Compositions and complexes of the invention are further capable of destroying microbial cells, such as bacteria, fungi, and protozoa, and destroying viruses. The compositions and complexes are also capable of modulating cell function in other ways.
