A new iron-based metal-organic framework with enhancing catalysis activity for benzene hydroxylation.

A new Fe-based metal-organic framework (MOF), termed Fe-TBAPy Fe(OH)(TBAPy)·4.4HO, was solvothermally synthesized. Structural analysis revealed that Fe-TBAPy is built from [Fe(OH)(CO)] rod-shaped SBUs (SBUs = secondary building units) and 1,3,6,8-tetrakis(-benzoate)pyrene (TBAPy) linker to form the topological structure highlighted by 7 Å channels and 3.

A new dimeric alkylresorcinol from the stem barks of (Anacardiaceae).

From an EtOAc-soluble fraction of the stem barks of (Anacardiaceae), one new dimeric alkylresorcinol named integracin E (), together with 4 known compounds (-) were isolated. Their chemical structures were elucidated based on the spectroscopic data interpretation. The absolute configuration of was determined by the specific rotation analysis of its acid-catalyzed hydrolysis product.

Combining Linker Design and Linker-Exchange Strategies for the Synthesis of a Stable Large-Pore Zr-Based Metal-Organic Framework.

A Zr(IV)-based metal-organic framework (MOF), termed reo-MOF-1 [ZrO(HO)(SNDC)], composed of 4-sulfonaphthalene-2,6-dicarboxylate (HSNDC) linkers and ZrO(HO)(CO) clusters was synthesized by solvothermal synthesis. Structural analysis revealed that reo-MOF-1 adopts the reo topology highlighted with large cuboctahedral cages (23 Å). This structure is similar to that found in DUT-52 (fcu topology), however, reo-MOF-1 lacks the body-centered packing of the 12-connected ZrO(OH)(CO) clusters, which is attributed to the subtle, but crucial influence in the bulkiness of functional groups on the linkers.
