Thioethers are good ligands for photoactivatable ruthenium(II) polypyridyl complexes, as they form thermally stable complexes that are prone to ligand photosubstitution. Here, we introduce a novel symmetric chelating bis(thioether) ligand scaffold, based on 1,3-bis(methylthio)-2-propanol (4) and report the synthesis and stereochemical characterization of the series of novel ruthenium(II) polypyridyl
trigger full activation of the Ru-based prodrug. Then, the blue light generated by TTA-UC liposomes under red light irradiation (630 nm, 0.57 W/cm2) through different thicknesses of pork or chicken meat was measured, showing that TTA-UC still occurred even beyond 10 mm of biological tissue. Overall, the rate of activation of the ruthenium compound in TTA-UC liposomes using either blue or red light (1.6 W/cm2)

UCNP to the ruthenium complex. Herein, we report on the synthesis and photochemistry of the ruthenium(II) polypyridyl complex [Ru(bpy)2(3H)](PF6)2 ([1](PF6)2), where bpy = 2,2-bipyridine and 3H is a photocleavable bis(thioether) ligand modified with two phosphonate moieties. This ligand was coordinated to the ruthenium center through its thioether groups and could be dissociated under blue-light irradiation

Five ternary complexes of palladium(II) namely [Pd(L(1))(2)](ClO4)(2) (1), [Pd(L(1))(L(2))](ClO4)(2) (2), [(PPh(3))(2)Pd(L(1))](ClO4)(2) (3), [(DppE)Pd(L(2))](ClO4)(2) (4) and [Pd(L(1))(L(3))](ClO4)(2) (5) where L(1) = MeSCH(2)CH(2)TeAr, L(2) = Me(2)NCH(2)CH(2)TeAr (Ar = 4-MeOC(6)H(4)) and L(3) = MeSCH(2)CH(OH)CH(2)SMe were synthesized by treating [PdCl2 . (L(1))] or [(PPh(3))(2)/(DPPE)PdCl2)] with AgClO4 and the appropriate ligand. The ligands L(1), L(2) and L(3) in these complexes are judged to be coordinated in bidentate mode on the basis of (1)HNMR and IR spectral data. All the complexes behave as 1:2 electrolytes in CH3CN. The Te-125(H-1) NMR spectra of 1 and 2 indicate that the ligands L(1) and L(2) in them are in a cis disposition in fleshly prepared dimethylsulphoxide-d(6)-CD3CN solutions, implying a similar configuration in the solid state but within a few hours there is partial conversion into the trans isomer.
