Postsynthetic ligand exchange for the synthesis of benzotriazole-containing zeolitic imidazolate framework.
The introduction of a triazole-based ligand to the zeolitic imidazolate framework-7 via a postsynthetic ligand exchange strategy not only maintains its framework, high stability and morphology, but also provides extra uncoordinated nitrogen atoms to improve the π-π and Lewis acid-base interactions.
متن کاملA hybrid zeolitic imidazolate framework membrane by mixed-linker synthesis for efficient CO2 capture.
A ZIF-9-67 hybrid membrane on α-Al(2)O(3) support was prepared using mixed-linker synthesis. The gas permeation and selectivity data demonstrate that this membrane may have potential applications for efficient CO(2) capture from several industrial mixtures.
متن کاملHybrid Zeolitic Imidazolate Frameworks : Controlling Framework Porosity and Functionality by Mixed - Linker Synthesis
A positive-tone, aqueous base soluble, polynorbornene (PNB) dielectric formulation has been developed. The photolithographic solubility switching mechanism is based on diazonaphthoquinone (DNQ) inhibition of polynorbornene resin functionalized with pendent hexafluoroisopropanol and carboxylic acid substituents. The optical contrast (at 365 nm) was found to be 2.3. The maximum height-to-width as...
متن کاملPorous Proton Exchange Membrane Based Zeolitic Imidazolate Framework-8 (ZIF-8)
Metal-organic frameworks (MOFs) are emerging material class for the past few years due to its tailorability characteristics for various applications. However, the research and development (R&D) of MOFs is still scarce for fuel cell system. This may be due to the several difficulties faced in selecting a good MOFs-based electrolyte, which consequently affects both proton conduction and methanol ...
متن کاملSelective Solvent-Assisted Linker Exchange (SALE) in a Series of Zeolitic Imidazolate Frameworks.
Solvent-assisted linker exchange (SALE) has recently emerged as an attractive strategy for the synthesis of metal-organic frameworks (MOFs) that are unobtainable via traditional synthetic pathways. Herein we present the first example of selective SALE in which only the benzimiadazolate-containing linkers in a series of mixed-linker zeolitic imidazolate frameworks (ZIF-69, -78, and -76) are repl...
