A strategy is proposed to construct oxygen-rich channel MOFs as chemosensors for sensing Fe3+ ions using oxygen-enriched multi-carboxylic acid ligands.

Dodecanuclear, icosanuclear and octanuclear porous MOF-like POMs materials [MoV12O12(μ2-O)4(μ3-O)12(Htrz)4(trz)4]∙nH2O (n = 22, 1; n = 92, 2; Htrz = 1H-1,2,3-triazole), [MoV8O8(μ2-O)12(Htrz)8]½∙[MoV12O12(μ2-O)4(μ3-O)12(Htrz)4(trz)4]∙44H2O (3), and [MoV8O8(μ2-O)12(Htrz)8]·62H2O (4) have been obtained and well...

Thefist interaction is in the bulk oilphase, where solution chemistry is involved. The second interaction occurs at the wear surfmes. Various experimental techniques [DSC, TFOUT, FRT, four ball) were used to measure interactions. In an examination of base oiladditive-interactions on oxidation stability, various species of base oils exert a strong inJuence on the performance of antioxidants. In additiveadditive interactions, the data suggest a strong concentration of dependent interaction patterns among the various additives and the base oils. Mechanistic studies are recommended to elucidate some of the observed phenonema
