A double-bent-mixed-ligand supported 2-periodic coordination polymer (CP) {[Zn2(FDA)2(4-abpt)2(H2O)2]}n (1) was synthesized from the unique combination of a bent furan-2,5-dicarboxylic acid (H2FDA) ligand and a bent 4-amino-3,5-bis(4-pyridyl)-1,2,4-triazole (4-abpt) coligand. The CP 1 demonstrates readily dispersible two-dimensional (2D) 2-periodic layer structure and considerable chemostability in aqueous media. Luminescence titration experiments indicate that CP 1 can serve as chemosensors for sensitively and selectively detecting Fe3+ cation, CrO42- and Cr2O72- anions in water solution via an environmentally friendly manner. Besides, the luminescent selective quenching mechanism of CP 1 toward Fe3+ cation, CrO42- and Cr2O72- anions is comprehensively studied in the light of absorption of the excitation energy of the host framework by individual analytes. In addition to this study using 4-Cyanopyridine, there are many other studies that have used 4-Cyanopyridine(cas: 100-48-1COA of Formula: C6H4N2) was used in this study.
4-Cyanopyridine(cas: 100-48-1) belongs to pyridine. The basicity and metallophilic high donor number of these π-deficient systems has long favored them as ligands in metal catalysis. The last decade saw pyridine assume a stronger role as functional group for directed C–H oxidation/activation.COA of Formula: C6H4N2
