Large pores generated by the combination of different inorganic units in a zinc hydroxide ethynylene diisophthalate MOF was written by Hausdorf, Steffen;Seichter, Wilhelm;Weber, Edwin;Mertens, Florian O. R. L.. And the article was included in Dalton Transactions in 2009.Safety of Dimethyl 5-ethynylisophthalate This article mentions the following:
A 5,5′-ethynylenediisophthalic acid linker mol. was synthesized and used to form a zinc carboxylate-based metal organic framework (MOF) with very large pores and unit cell volume resulting from the unusual combination of structurally different inorganic units forming the secondary building blocks (SBUs). The structure is the first zinc hydroxide carboxylate structure where the inorganic units do not form layers or ribbons but isolated islands. The structure forms true pores with a significantly narrowed pore entry similar to zeolites. The pores are, thus, not created simply by intersecting channels as in most other MOF structures. Although the pore shape is highly asym. the spherical free volume is with 10.8 Å still large. The stability of the SBUs in respect to exchange and removal of coordinated solvent mols. was studied. In the experiment, the researchers used many compounds, for example, Dimethyl 5-ethynylisophthalate (cas: 313648-56-5Safety of Dimethyl 5-ethynylisophthalate).
Dimethyl 5-ethynylisophthalate (cas: 313648-56-5) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Safety of Dimethyl 5-ethynylisophthalate
