| titleOfInvention | Binuclear terbium (III) coordination polymer and preparation method and application thereof |
| abstract | The invention discloses a binuclear terbium (III) coordination polymer, a preparation method and application thereof, and a complexThe chemical formula of (A) is: [ Tb ] 2 (HPIDC)(C 2 O 4 ) 2 (H 2 O) 3 ·2H 2 O] n In which H is 3 PIDC is 2- (2-pyridyl) -1H-imidazole-4, 5-dicarboxylic acid, H 2 C 2 O 4 Is oxalic acid. The preparation method of the coordination polymer comprises the following steps: converting TbCl 3 And H 3 PyIDC，H 2 C 2 O 4 And (3) adding the following components in percentage by weight of 2: 1:1 is soluble in H 2 Adding KOH solution into the mixed solution of O/ethanol (V: V ═ 1: 1), adjusting the pH to 4, and reacting for 72 hours at 160 ℃ in a hydrothermal reaction kettle. Cooling to room temperature to obtain light yellow bulk crystal, washing with mixed solvent of water and ethanol, washing with diethyl ether, and vacuum drying. The yield was 57.5%. The complex structure comprises terbium ions in two coordination modes, and ligands are respectively HPIDC 2‑ And C 2 O 4 2‑ The anion is a three-dimensional coordination polymer. The coordination polymer is used as a solid luminescent material, is excited by light with a wavelength of 330nm, and can emit green light for a sample, the color coordinate is (0.284, 0.523), the fluorescence quantum yield is 34.7%, and the fluorescence lifetime is 1.32 ns. |
