In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Triazine-Cored Lanthanide-Based Metal-Organic Frameworks Featuring Unique Water Chains and Strong Characteristic Emissions, published in 2019, which mentions a compound: 3685-23-2, Name is cis-4-Aminocyclohexane carboxylic acid, Molecular C7H13NO2, Quality Control of cis-4-Aminocyclohexane carboxylic acid.
A new triazine-cored tricarboxylic acid, N,N’,N”-1,3,5-triazine-2,4,6-triyltris(cis-4-aminocyclohexane-carboxylicacid)(H3L), was prepared by replacing the chlorine atoms of cyanuric chloride with cis-4-aminocyclohexane-carboxylic acid, which was used for the construction of a series of triazine-cored lanthanide-based metal-organic frameworks (MOFs). All these MOFs were structurally authenticated, revealing that they are isostructural and exist as two-dimensional (2D) coordination networks with the general formula [Ln(L)(H2O)2]·5.5 H2O (Ln = 1·Gd, 2·Tb, 3·Eu). A unique one-dimensional water chain, composed of primary tetrameric cyclic rings and dodecameric cyclic rings, was found entrapped in the lattice. Moreover, all these compounds display bright characteristic photoluminescence. Particularly, for 1, apart from the strong blue emission peak (Φf = 20.6 %) corresponding to the intraligand transition under near-UV excitation, the characteristic emissions of Gd3+ cation (Φf = 5.0 %) were unexpectedly observed upon excitation at 273 nm.
In some applications, this compound(3685-23-2)Quality Control of cis-4-Aminocyclohexane carboxylic acid is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
