A salophen cobalt(II) complex enables water oxidation at neutral pH in photoactivated sacrificial cycles under visible light, thus confirming the high appeal of earth abundant single site catalysis for artificial photosynthesis.

A novel method for the rapid extraction and determination of a ppt level of Pb2+ and Cu2+ ions using partial silylated MCM-41 modified by a new salophen and inductively coupled plasma atomic emission spectrometry (ICP-AES) is introduced. The preconcentration factor of the method is 500, and the detection limits of Pb2+ and Cu2+ are 335 and 34 ng L(-1), respectively. The time and efficiency of e...

The use of micelles to transpose lipophilic receptors, such as uranyl-salophen complexes, into an aqueous environment is a valuable and versatile tool. Receptor 1 incorporated into CTABr micelles forms a supramolecular system that exhibits excellent binding properties towards fluoride in water, despite the competition of the aqueous medium. To fully evaluate the potential of micellar nanodevice...

The title compound, [Co(C(20)H(14)N(2)O(2))(C(5)H(5)N)(2)]ClO(4) or [Co(salophen)(py)(2)]ClO(4), where salophen is o-phenyl-enebis(nitrilo-methyl-idyne)]diphenolate and py is pyridine, contains a six-coordinate mononuclear cobalt(III) atom. The two phenolic O atoms and the two imine N atoms are located in cis positions. There are two pyridine mol-ecules attached to the metal atom, filling the a...

 This research applied a nanostructured electrochemical sensor with screen-printed electrode (SPE) for examining the dopamine (DA) electrocatalytic oxidation when uric acid (UA) was present. Cu(salophen) modified SPE Cu(salophen)/SPE employed to investigate behavior of DA. At optimal pH (pH 7.0), DA at takes place potential around 100 mV less positive than unmodified SPE. Chronoamperomet...

Single-atom catalysts are a family of heterogeneous electrocatalysts widely used in energy storage and conversion. The determination the local structure active metal sites is challenging, which limits establishment reliable structure-property relationship single-atom catalysts. A carbon black-conjugated complex can be as model catalyst to probe intrinsic activity with certain structures. In thi...

The electrochemical reduction of CO2 to methanol is a potentially cost-effective strategy reduce the concentration this greenhouse gas while at same time producing value-added chemical. Herein, we detail highly efficient 2D nickel organic framework containing large density dispersed salophen NiN2O2 active sites toward CO2RR methanol. By tuning ligand environment NiN2O2, electrocatalytic activit...

Quinolines are common pharmacophores present in numerous FDA-approved pharmaceuticals and other bioactive compounds. Here, we report the design and development of new o-quinone-based catalysts for the oxidative dehydrogenation of tetrahydroquinolines to afford quinolines. Use of a Co(salophen) cocatalyst allows the reaction to proceed efficiently with ambient air at room temperature. The utilit...
