A series of metal–organic loops templated by [SiMo₁₂O₄₀]⁴⁻ and [β-Mo₈O₂₆]⁴⁻ anions using double chelating ligands: amperometric sensing and selective photocatalytic properties

Abstract

By changing the POM anions and TM ions, a series of compounds with multi-nuclear loops was formed.

A series of POM compounds constructed using a flexible ligand containing three coordination groups: electrocatalytic and photocatalytic reduction and amperometric detection of Cr(vi)

“…It is due to two consecutive two-electron processes of the Mo 8 anion. 23 When the scan rate is gradually increased from 20 to 500 mV s −1 , the cathode peaks shift to the negative potential direction, and the anode peaks shift to the positive potential direction. When the scan rates are lower than 100 mV s −1 , the peak currents are proportional to the scan rates, indicating that the redox process of 1 – to 3 –CPEs is surface-confined.…”

POM-based compounds modified by mono- and bis-triazole derivatives: photocatalytic, electrochemical, and supercapacitor properties

“…29 In the potential range from +500 to −50 mV for 3-CPE, there exist two reversible redox peaks I-I′ and II-II′ for 3-CPE with means peak potentials E 1/2 = (E pa + E pc )/2 at +211 and +97 mV (scan rate: 200 mV s −1 ), corresponding to two consecutive two-electron processes of the Mo 8 anion. 30 For 5-CPE, in the potential range from +400 to −900 mV for 5-CPE, there exist ). These three redox peaks are attributed to the two consecutive oneelectron and one two-electron processes of PW 12 .…”

Two rare {M2(MoO4)2}n chain-containing molybdate-based metal–organic complexes with a bis-pyrazole-bis-amide ligand: fluorescent sensing and photocatalysis performance

“…Currently, as an important research branch of polyoxometalate (POM) chemistry, polyoxomolybdate-based metal-organic complexes (MOCs) have attracted numerous researchers' attention, not only due to their diverse structures caused by different amounts of molybdenum centers, [1][2][3][4][5][6][7] but also their outstanding properties in the elds of electrochemistry, medicine, uorescence, materials and photocatalysis, et al 8,9 During the synthesis of these MOCs, the polyoxomolybdates, including [ 4À and so on, [10][11][12][13] can be usually produced by changing reaction conditions or raw materials. Among them, the {MoO 4 } unit-containing MOCs are of interest, which can be converted from different raw materials.…”
