Fully dispersed nano-size zeolitic imidazolate frameworks embedded in PBI have been used in gas separation membranes [26]. The loading with these specific nanoparticles overcomes the low permeability of neat PBI. The membranes exhibit high transparency and mechanical flexibility, and an enhanced... 

A few examples of 2-spiroindoline 2f/-chromenes were reported from the condensation of l,3,3-trimethyl-2-methyleneindoline with salicylalde-hydes, under microwave irradiation in solvent-free conditions (14H(89)1017). [3 + 3] Cycloaddition reactions of a,p-unsaturated aldehydes with cyclohexane-1,3-dione or 4-pyran-3,6-dione mediated by a zeolitic imidazolate framework nanosphere gave access to 2,2-disubstituted tetrahydro- or hexahydro-2f/-chromenes, respectively (14JA13963).

The presence of water vapour will define which materials can be used based on their hydrolytic stability. As an example metal-organic frameworks (MOFs) and covalent organic framework (COFs) are crystalline microporous materials which can exhibit exceptionally high surface areas and gas sorption capacities and, as such, have been proposed as potential materials for CCS. However, some of these materials can be unstable in the presence of moisture. The IRMOF series and the more recently produced COF materials are particularly unstable (e.g., loss of porosity at room temperature in air). Clearly, materials of this type would be unsuitable for CCS application. If such materials are to be used, more stable types are required for example, one class of MOF known as zeolitic imidazole frameworks (ZIFs) are reported to have greatly improved hydrolytic stability. 

Yaghi and coworkers have demonstrated the versatility of the edge-expansion approach through synthesis of a large family of zeolitic imidazolate frameworks (ZIFs), Figme 25, for example. The ZIFs obtained include both previously known zeolitic topologies such as SOD, RHO, ANA, BCT, DFT, GME, GIS, MER, and LTA, as well as novel ones such as POZ and MOZ. ... 

Recently developed zeolitic imidazole frameworks (ZIFs) have shown high affinity for CO2 and can capture CO2 from CO2/CO, CO2/N2, and CO2/CH4 mixtures. ZIFs... 

It turns out that compressing MOF materials to very high pressures gives results that are much more significant than just academic curiosity. Similar experiments performed on the zeolitic imidazolate framework known as ZIF-8 [(Zn(meim)2], meim = 2-methylimidazolate again show expansion at modest pressures as the PTM is squeezed into the cavities, but at 1.5 GPa the material undergoes a phase transition...
