Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 553-53-7, Name is Nicotinohydrazide. In a document, author is Chen, Yong-Qiang, introducing its new discovery. Recommanded Product: Nicotinohydrazide.
Cd-II-Organic Frameworks Fabricated with a N-Rich Ligand and Flexible Dicarboxylates: Structural Diversity and Multi-Responsive Luminescent Sensing for Toxic Anions and Ethylenediamine
Three metal-organic frameworks {[Cd(L)(glu)].3 H2O}(infinity) (1), {[Cd-2(L)(2)(adi)(2)].5 H2O}(infinity) (2) and {[Cd(L)(sub)].3 H2O.DMA }(infinity) (3) (L=pyridine-3,5-bis(5-azabenzimidazole), H(2)glu=glutaric acid, H(2)adi=adipic acid and H(2)sub=suberic acid) were obtained under solvothermal conditions. Complex 1 shows a 2D (4,4) network constructing of Cd-2-glu and Cd-L chains. Complex 2 presents a 2-fold interpenetrating 3D framework with pcu topology. Complex 3 is a 3D framework with cds topology. Three complexes with versatile structures were obtained by changing aliphatic dicarboxylate ligands with different lengths based on a N-rich ligand. Moreover, the fluorescence measurements indicate that complex 1 is a good multifunctional chemosensor for the detection of Cr2O72- and MnO4- anions by fluorescence quenching effect, and ethylenediamine by fluorescence enhancement effect, with detection limits of 1.196 ppm, 0.551 ppm and 64.572 ppm, respectively. Both complexes 2 and 3 can selectively sense Cr2O72- anion with detection limits of 1.126 ppm for 2 and 0.831 ppm for 3 by a fluorescence quenching effect.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 553-53-7 help many people in the next few years. Recommanded Product: Nicotinohydrazide.
