Terpyridine derivatives as turn-on fluorescence chemosensors for the selective and sensitive detection of Zn2+ ions in solution and in live cells

A terpyridine based compound L1 was designed and synthesized as an off-on chemosensor for the detection of Zn2+. Chemosensor L1 showed excellent selectivity and sensitivity toward Zn2+ by exhibiting a large fluorescence enhancement (～51-fold) at 370 nm whereas other competitive metal ions did not show any noticeable change in the emission spectra of chemosensor L1. The chemosensor (L1) was shown to detect Zn2+ ions down to 9.76 μM at pH 7.4. However, chemosensor L1 binds Zn2+ in a 1:2 ratio (receptor:metal) with an association constant of 1.85 × 104 (R2 = 0.993) and this 1:2 stoichiometric fashion is established on the basis of a Job plot and mass spectroscopy. DFT/TD-DFT calculations were carried out to understand the binding nature, coordination features and electronic properties of L1 and the L1-2Zn2+ complex. In addition, this turn-on fluorescence probe was effectively used to image intracellular Zn2+ ions in cultured MDA-MB-468 cells.

Catalytic Water-Oxidation Activity of a Weakly Coupled Binuclear Ruthenium Polypyridyl Complex

The catalytic oxidation of water by the binuclear complex [Ru2(H2O)2(bpy)2(tpy2ph)](PF6)4[bpy = 2,2′-bipyridine; tpy2ph = 1,3-bis(4′-2,2′:6′,2′′-terpyridin-4-yl)benzene] was investigated comparatively to its mononuclear counterpart [Ru(H2O)(bpy)(phtpy)](PF6)2(phtpy = 4′-phenyl-2,2′:6′,2′′-terpyridine). These catalysts were prepared from the synthesis of their precursor chloride complexes, which were also extensively characterized in this work. The H2O–RuIIcomplexes were found to undergo proton-coupled electron-transfer processes to generate the redox species HO–RuIII, O=RuIV, and O=RuV. The catalytically active species, [RuV2(O)2(bpy)2(tpy2ph)]6+and [RuV(O)(bpy)(phtpy)]3+, were generated electrochemically and by using cerium(IV) ammonium nitrate. In the presence of CeIV, the catalytic rates for O2production by the binuclear and mononuclear species were 1.9 × 10–3and 9.5 × 10–5s–1, respectively. This superior catalytic performance of the binuclear complex suggests that, despite weak electronic coupling between the Ru centers, the second site could play an important mechanistic role in the formation of the activated species [(bpy)(OO)RuIV(tpy2ph)RuIII(OH)(bpy)]4+.
