A highly porous NbO type metal-organic framework constructed from an expanded tetracarboxylate was written by Cai, Jianfeng;Rao, Xingtang;He, Yabing;Yu, Jancan;Wu, Chuande;Zhou, Wei;Yildirim, Taner;Chen, Banglin;Qian, Guodong. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2014.Name: Dimethyl 5-ethynylisophthalate This article mentions the following:
A novel NbO type microporous metal-organic framework Cu2L (ZJU-32 (5); H4L (4) = 5′-((3,5-dicarboxyphenyl)ethynyl)-[1,1′:3′,1”-terphenyl]-4,4”-dicarboxylic acid) constructed from an elaborately designed tetratopic ligand was solvothermally synthesized and structurally characterized. The activated ZJU-32a exhibits high permanent porosity with the Brunauer-Emmett-Teller (BET) surface area of 3831 m2 g-1 and the pore volume of 1.482 cm3 g-1, enabling it to be a promising material for both methane storage and carbon dioxide capture at room temperature In the experiment, the researchers used many compounds, for example, Dimethyl 5-ethynylisophthalate (cas: 313648-56-5Name: 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. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides. Name: Dimethyl 5-ethynylisophthalate
