Attaching molecular catalysts to metal and semiconductor electrodes is a promising approach to developing new catalytic electrodes with combined advantages of molecular and heterogeneous catalysts. However, the effect of the interfacial electric field on the stability, activity, and selectivity of the catalysts is often poorly understood due to the complexity of interfaces. In this work, we examine the strength of the interfacial field at the binding site of CO2 reduction catalysts including Re(S-2,2?-bipyridine)(CO)3Cl and Mn(S-2,2?-bipyridine)(CO)3Br immobilized on Au electrodes. The vibrational spectra are probed by sum frequency generation spectroscopy (SFG), showing pronounced potential-dependent frequency shifts of the carbonyl stretching modes. Calculations of SFG spectra and Stark tuning rates based on density functional theory allow for direct interpretation of the configurations of the catalysts bound to the surfaces and the influence of the interfacial electric field. We find that electrocatalysts supported on Au electrodes have tilt angles of about 65-75 relative to the surface normal with one of the carbonyl ligands in direct contact with the surface. Large interfacial electric fields of 108-109 V/m are determined through the analysis of experimental frequency shifts and theoretical Stark tuning rates of the symmetric CO stretching mode. These large electric fields thus significantly influence the CO2 binding site.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

A novel fluorine-18 method employing rhenium(i) mediation is described herein. The method was found to afford moderate to high radiochemical yields of labelled rhenium(i) complexes. Subsequent thermal dissociation of the complexes enabled the radiosynthesis of fluorine-18 labelled pyridine bidentate structures which could not be radiofluorinated hitherto. This rhenium(i) complexation-dissociation strategy was further applied to the radiosynthesis of [18F]CABS13, an Alzheimer’s disease imaging agent, alongside other 2,2?-bipyridine, 1,10-phenanthroline and 8-hydroxyquinoline labelled radiotracers. Computational modelling of the reaction mechanism suggests that the efficiency of rhenium(i) activation may be attributed to both an electron withdrawal effect by the metal center and the formation of an acyl fluoride intermediate which anchors the fluoride subsequent to nucleophilic addition.

6,6′-Diamino-2,2′-bipyridine (1a) has been found to exhibit a strong fluorescence in the near-UV region.Some amino and/or chloro substituted bipyridines (bpys) have been synthesized an studied to show that only 6-amino-substtuted derivatives exhibited a strong emission.The emission of 6-amino-6′-chloro-bpy (3a) was the strongest (lambdamax = 429.0 nm; Phi = 0.78 in ethanol) among them.On the other hand, little or no emission was observed for monochloro-, dichloro- and 4-amino- derivatives.

Synthetic strategies for preparing BEDT-TTF derivatives functionalised with metal ion binding groups

The syntheses of BEDT-TTF (ET) derivatives with potential metal ion binding pyridyl, bipyridyl and terpyridyl groups is achieved either by stepwise construction of the organosulfur core or via reactions of hydroxymethyl-ET for which a cheap and efficient four step route is reported. The tosylate of hydroxymethyl-ET, reported for the first time, undergoes nucleophilic substitutions with pyridyl, bipyridyl- and terpyridyl-thiolates to give new donors. The X-ray crystal structures of two substituted ET derivatives show considerable deviation of the organosulfur donor system from planarity by bending about the short molecular axis of the ET group.

0.303 g (9.45¡Á10-4 mol) of compound 1 and 2 g of KOH were stirred in 10 mL of DMSO for 10 min. 0.645 g (3.38¡Á10-3) of 4-chloro-2,2′-bipyridine was added. The reaction mixture was continuously stirred under argon at 50 C. for 22 hrs. After reaction, the mixture was poured into 30 mL of water. Extraction with 100 mL of CH2Cl2 was tried when the solution was highly alkaline but it was found difficult to separate the two phases. After evaporation of CH2Cl2, the oil was purified by chromatography (silica gel treated with 20% triethylamine in hexane, elution 5-10% methanol in CH2Cl2 and pure methanol) and vacuum dried to afford a sticky transparent product. This was dissolved in methanol and precipitated in acidified water to yield 52 mg of white powder. The remaining water phase was adjusted to pH=8 with NH3H2O. The solution was further extracted with CH2Cl2 until no more bipyridine derivatives could be detected by TLC. After evaporation of CH2Cl2, the oil was purified by chromatography (silica gel treated with 20% triethylamine in hexane, elution 5-10% methanol in CH2Cl2, and pure methanol), vacuum dried and precipitated in acidified water to yield 223 mg of product.
