Lanthanide complexes of polycarboxylate-bearing dipyrazolylpyridine ligands with near-unity luminescence quantum yields: the effect of pyridine substitution was written by Brunet, Ernesto;Juanes, Olga;Sedano, Rosa;Rodriguez-Ubis, Juan-Carlos. And the article was included in Photochemical & Photobiological Sciences in 2002.Product Details of 408352-58-9 This article mentions the following:
The title complexes displayed a marked dependence of their luminescence properties upon pyridine substitution. The ligand with the 4-carbamoyl-substituted pyridine showed a long-lived luminescence of near-unity quantum yield for Tb3+ and quite reasonable values for Eu3+, Sm3+ and Dy3+, thus making it an excellent candidate for a luminescent probe to be attached to biomols. by a peptide-like linkage. In the experiment, the researchers used many compounds, for example, 2,6-Dibromoisonicotinonitrile (cas: 408352-58-9Product Details of 408352-58-9).
2,6-Dibromoisonicotinonitrile (cas: 408352-58-9) belongs to pyridine derivatives. Pyridine’s the lone pair does not contribute to the aromatic system but importantly influences the chemical properties of pyridine, as it easily supports bond formation via an electrophilic attack. Several pyridine derivatives play important roles in biological systems. While its biosynthesis is not fully understood, nicotinic acid (vitamin B3) occurs in some bacteria, fungi, and mammals.Product Details of 408352-58-9
