A series of lanthanide coordination polymers (Ln-CPs), with the formula of {[Ln(L)3(CH3OH)(H2O)]n} (Ln = Sm (1), Eu (2), HL = 2-chloroisonicotinic acid) and {[Ln(L)3(H2O)2]n} (Ln = Dy (3), Tb (4)), were synthesized under solvothermal condition. This series display two different 1D chains due to the lanthanide contraction: complexes 1 and 2, based on light Sm and Eu, resp., consist of paddle-wheel [Ln2(COO)4] dimmers through double μ2-COO bridges, and complexes 3 and 4 with heavy Dy and Tb, resp., show 1D [Ln(COO)2]n chains. The luminescent measurements indicate the typical emissions of corresponding Ln3+ ions in complexes 1-4. Furthermore, complexes 2 and 4 display significant luminescent response for Fe3+ ions with high quenching constant Complexes 2 and 4 can act as luminescent probes for Fe3+ ions with relatively high sensitivity and selectivity. In the experimental materials used by the author, we found 2-Chloroisonicotinic acid(cas: 6313-54-8COA of Formula: C6H4ClNO2)
2-Chloroisonicotinic acid(cas: 6313-54-8) belongs to pyridine. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. As ligands, solvents, and catalysts they facilitate reactions; thus descriptions of these new ligands and their applications abound each year.COA of Formula: C6H4ClNO2
