A 3D Iodoplumbate Semiconducting Open Framework with Visible-light-induced Photocatalytic Performance.

Employing in situ N-alkylation of the conjugated compound 9,10-bis(4-pyridyl)anthracene (bpanth) as structure-directing agent, a 3D inorganic-organic hybrid iodoplumbate, [Me (bpanth)][Pb I ] (1), was solvothermally prepared. The in situ N-alkylation of bpanth with alcohols was investigated. 1 features a novel 3D open framework based on an interesting Pb I cluster.

Zeolitic Open-Framework Borates with Noncentrosymmetric Structures and Nonlinear Optical Properties.

Three zeolitic pentaborates (Hen)[BO(OH)] (1, en = ethylenediamine), (Hen)[Al(BO)] (2), (Hen)[NH(CH)][Al(BO)] (3) were solvothermally obtained by employing ethanediamine molecules as structure-directing agents (SDAs). The nonmetal borate of 1 features a noncentrosymmetric two-dimensional layered structure. Through introducing Al atoms as the linkers and regulating the reaction conditions of 1, two three-dimensional zeolitic open-framework aluminoborates, noncentrosymmetric (NCS) of 2 and centrosymmetric (CS) of 3, were achieved.

Three-Shell Cu@Co@Ni Nanoparticles Stabilized with a Metal-Organic Framework for Enhanced Tandem Catalysis.

Transition-metal catalysts, particularly featuring a triple-layered core-shell structure, are very promising for practical application; however, reports on their synthesis and catalytic application for a cascade reaction were very rare. In this work, tiny Cu@Co@Ni core-shell nanoparticles (∼3.3 nm) containing Cu core, Co middle shell, and Ni outer shell stabilized by metal-organic framework (MOF) were successfully synthesized to give a quadruple-layered Cu@Co@Ni/MOF at moderate conditions.

Tripyridine-Derivative-Derived Semiconducting Iodo-Argentate/Cuprate Hybrids with Excellent Visible-Light-Induced Photocatalytic Performance.

Through regulating the pH values, a series of iodo-argentate/cuprate hybrids, [Me (4-TPT)] [Ag I ] (1, Me (4-TPT)=N,N',N''-trimethyl-2,4,6-tris(4-pyridyl)-1,3,5-triazine), [Me (4-TPT)][M I ] (M=Ag/2, Cu/2 a), [Me (3-TPT)][M I ] (Me (3-TPT)=N,N',N''-trimethyl-2,4,6-tris(3-pyridyl)-1,3,5-triazine, M=Ag/3, Cu/4), which exhibit adjustable structural variations with different dimensional structures, have been obtained under solvothermal conditions. They are directed by two types of in situ N-alkylation TPT-derivatives (Me (4-TPT) for 1/2/2 a and Me (3-TPT) for 3/4) and represent the isolated units (1), 1D polymeric chain (4), 2D layered structures (2/2 a, 3) based on diverse metal iodide clusters. These compounds possess reducing band gaps as compared with the bulk β-AgI and CuI and belong to potential semiconductor materials.
