2-(Anthracen-9-ylmethylene)malononitrile (cas: 55490-87-4) belongs to nitriles. Nitriles are polar, as indicated by high dipole moments. As liquids, they have high relative permittivities, often in the 30s. Some nitriles are manufactured by heating carboxylic acids with ammonia in the presence of catalysts. This process is used to make nitriles from natural fats and oils, the products being used as softening agents in synthetic rubbers, plastics, and textiles and for making amines.Recommanded Product: 55490-87-4

Bifunctional design of stable metal-organic framework bearing triazole-carboxylate mixed ligand: Highly efficient heterogeneous catalyst for knoevenagel condensation reaction under mild conditions was written by Liu, Feixiong;Kumar, Sandeep;Li, Shuangshuang;You, Hengzhi;Ren, Peng;Zhao, Limin. And the article was included in Catalysis Communications in 2020.Recommanded Product: 55490-87-4 This article mentions the following:

A highly water stable zinc metal-organic framework (ZnMOF), {[Zn(HL)2]}n, was synthesized using a triazole-carboxylate-based mixed ligand (L = 5-(4H-1,2,4-triazol-4-yl)isophthalic acid). A 2D MOF was formed by hydrothermal synthesis, and extended to a 3D supramol. network through strong hydrogen bonding. This MOF was fully characterized by Fourier-transformation IR spectroscopy, thermogravimetric anal., single-crystal X-ray diffraction (XRD), powder XRD and elemental anal. Owing to the d10 configuration of this ZnMOF, its luminescent properties were suitable for the sensing of the CN– ions over other anions, as inferred from the florescence result. However, regarding the catalytic mechanism, this ZnMOF showed a strong ability to react with CN–, which might be due to the hydrogen bonding between the COOH groups without coordination. This interaction behavior with CN– ions makes the ZnMOF a promising heterogeneous catalyst for Knoevenagel condensations using malononitrile and aldehyde derivatives as reactants under mild conditions. All reactions were conducted in water as a green solvent. In the experiment, the researchers used many compounds, for example, 2-(Anthracen-9-ylmethylene)malononitrile (cas: 55490-87-4Recommanded Product: 55490-87-4).
