Cobalt complexes tuned by Anderson-type polyoxometalates and bis-amide derivative ligands featuring a ‘V’-like connector for efficient ampere sensing and the visible-light catalytic reduction of Cr(vi)

Abstract

Four cobalt(ii) complexes assembled from two new bis-amide derivative N-donor ligands and Anderson-type polyoxometalates display excellent electrochemical sensing and photocatalytic reduction activities toward Cr(vi) ions.

Four New Terpyridine Complexes Based Polyoxometalates with [W10O32]4– Anions as High‐Efficiency Dual‐Site Catalysis for Thioether Oxidation Reaction†

“…There have been many reports on the modification of polyacids by using complexes as cations. [ 19‐20 ] In particular, triazole, [ 21 ] bithiazole, [ 22 ] tetrazole, [ 23 ] and amide derivatives [ 24 ] are often used as the ligands to form complex cations and combine with POMs anions, and show good properties of electrocatalysis, [ 25 ] photocatalysis, [ 26 ] thermocatalytic [ 27 ] and biological activities, [ 28 ] etc . Terpyridyl derivative (TPY) is a chelating ligand with three nitrogen atoms, which can be used to construct the complexes by regulating different synthesis conditions.…”

New pyrimidine-amide-tetrazole ligand derived polyoxometalate-based copper complexes as catalysts for sulfide-sulfoxide transformation and electrochemical sensors

“…For example, our group obtained two new POMOCs by introducing the V-shaped diamide ligand into the Anderson-type POM system, which showed satisfactory performances in photocatalytic reduction and electrochemical detection of Cr( vi ). 27…”
