A series of photoactive complexes of [Ru II bis(bipyridyl){2-(4-methylpyridin-2-yl)benzo[d]-X-azole}](PF 6 ) 2 (X = N-CH 3 , 1; S, 2; or O, 3) have been synthesized and fully characterized by proton and 13 C NMR spectroscopy and UV/Vis spectroscopy. The X-ray structure of 1 is also reported. The electrochemical behavior and the photophysical properties of 1-3 have been investigated. Cyclic voltammetry (CV) reveals the presence of three consecutive one-electron reduction processes and a single one-electron oxidation process that
The synthesis and physical-chemical characterization of the metal-ligand complex [Os(bpy)2(CO)(enIA)][OTf]2 (where enIA = ethylenediamine iodoacetamide) with a sulfhydryl-specific functional group is described. The UV and visible absorption and luminescence emission, including lifetime and steady-state anisotropy, are reported for the free probe and the probe covalently linked to two test proteins. The spectroscopic properties of the probe are unaffected by chemical modification and subsequent covalent linkage to the proteins. The luminescence lifetime in aqueous buffer is approximately 200 ns and the limiting anisotropy is greater than 0.125, suggesting a potentially useful probe for biophysical investigations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
