Toluene-assisted synthesis of RHO-type zeolitic imidazolate frameworks: synthesis and formation mechanism of ZIF-11 and ZIF-12.
Toluene was discovered as the structure template for the synthesis of large-cage RHO-type zeolitic imidazolate frameworks (ZIF-11 and ZIF-12) in an alcohol-based solution where benzimidazole-toluene interactions play a decisive structure-directing role; otherwise it leads to small-cage SOD-type ZIF-7 and ZIF-9 without toluene. The specific π-π interactions make toluene molecules adopt a specifi...
متن کاملCarbon dioxide sensitivity of zeolitic imidazolate frameworks.
Zeolitic imidazolate frameworks of zinc, cobalt, and cadmium, including the framework ZIF-8 commercially sold as Basolite Z1200, exhibit surprising sensitivity to carbon dioxide under mild conditions. The frameworks chemically react with CO2 in the presence of moisture or liquid water to form carbonates. This effect, which has been previously not reported in metal-organic framework chemistry, p...
متن کاملSynthesis, structure, and carbon dioxide capture properties of zeolitic imidazolate frameworks.
Zeolites are one of humanity's most important synthetic products. These aluminosilicate-based materials represent a large segment of the global economy. Indeed, the value of zeolites used in petroleum refining as catalysts and in detergents as water softeners is estimated at $350 billion per year. A major current goal in zeolite chemistry is to create a structure in which metal ions and functio...
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 کاملControl over Porosity using Isoreticular Zeolitic Imidazolate Frameworks (IRZIFs) as Template for Porous Carbon Synthesis
Herein, using Isoreticular Zeolitic Imidazolate Frameworks (IRZIFs) as template, we report the synthesis, morphology and gas adsorption properties of porous carbon synthesized by nanocasting method at 1000 C, where furfuryl alcohol (FA) has been used as a carbon source. Using IRZIFs with variable porosity as templates, we could achieve the control over carbon porosity, H2 and CO2 uptake. The r...
