Synthesis and Luminescent Properties of a Novel Nanoscale Eu(III)-Carboxylate Coordination Polymer
Abstract:
To prepare nanoscale coordination polymers (NCPs) which can exhibit intense luminescence have attract an increasing interest. In this paper, we present the synthesis of a novel example of discus-like luminescent nanoscale Eu (III)-carboxylate coordination polymers. The organic ligand is a derivative of terephthalate (Na2L) with a big side group. The Eu (III)-L NCPs was synthesized through microemulsion method, and the morphology can alter along with the changing of metal: ligand ratios. XRD results reveal that the self-assembled disk-like NCPs exhibit long-range ordered structures. The luminescent measurements showed that the resultant NCPs not only exhibits typical fluorescence of Eu (III), but also can maintain the inherent fluorescence of the ligands.
