Polyoxometalate immobilization in CuI/Ag–pz porous coordination polymers: The influences of them on the structural properties of frameworks
چکیده انگلیسی

Three new high dimensional CuI/Ag–pz porous coordination polymers (PCPs) with different Keggin polyoxometalate templates have been hydrothermally synthesized: [CuI5(pz)6Cl][HPMoVI10MoV2O40] (1) [Ag5(pz)7(BW12O40)] (2) and [CuI5(pz)6H(H2W12O40)]·4H2O (3) (pz=pyrazine). The choice of the particular Keggin POM templates is shown to influence the structural properties of the Cu/Ag PCPs. Compound 1 shows a Cl-bridged Cu–pz–Cl double layer, between which two kinds of [HPMoVI10MoV2O40]4−(PMo12) polyanions are located. Compound 2 presents a 3D Ag–pz framework with parallelogram-like voids, into which BW12O405− (BW12) Keggin ions are incorporated. Compound 3 contains a Cu–pz cationic layer framework, between which are located [H(H2W12O40)]5− (W12) Keggin ions. Primary photocatalytic experiment indicates that compound 1 presents excellent photocatalytic activity. The photoluminescence properties and electrochemistry properties of the compounds are also discussed.

The choice of the particular Keggin template is shown to influence the structural properties of the Cu/Ag PCPs. Their photocatalytic activities have been studied.Figure optionsDownload as PowerPoint slideHighlights
► In this paper, three Keggin POM-templated metal-pyrazine frameworks are reported.
► The choice of template can influence the structural properties of the frameworks.
► Further, compound 1 exhibits excellent photocatalytic activity.
