AI Article Synopsis
- Four novel coordination polymers (CPs) were created using [2,2'-bifuran]-5,5'-dicarboxylic acid and metal ions (Zn, Cd, Co).
- Their structures were identified via crystallographic analysis, showing different frameworks: complex (2) has a two-dimensional structure while the others are one-dimensional.
- Both complexes (2) and (3) exhibit blue-shifted light emission based on the ligand, with similar lifetimes to that of the ligand itself, confirming that the emission comes from the ligand.
Article Abstract
Four novel coordination polymers (CPs) assembled with [2,2'-bifuran]-5,5'-dicarboxylic acid (HL) and metal ions Zn, Cd or Co have been successfully synthesized. Their molecular structures have been determined to be Zn(L)(HO) (1), [Zn(L)(DMF)] (2), [Cd(L)(EtOH)(DMF)] (3) and Co(L)(HO)·(HO) (4) by crystallographic analysis. It is found that (2) exhibits a two-dimensional infinite framework, whereas the others exhibit a one-dimensional framework. Both (2) and (3) exhibit ligand-based emission which is blue-shifted compared with the emission from the HL ligand. Time-resolved spectroscopic measurement reveals that the complexes exhibit a similar lifetime with that of the ligand, which confirms that the emission of the complexes originates from the ligand.
