铽(Ⅲ)、铕(Ⅲ)-1-环丙基-6-氟-7(1-哌嗪基)1、4-二氢-4-氧喹啉-3-羧酸-乙酰丙酮三元固体荧光配合物的合成与光谱表征

Two ternary solid complexes， Tb³⁺ (Eu³⁺)-ciprofloxacina-acetylacetone， have been synthesied and chara-cterized by elemental analysis， IR. Ciprofloxacina is one kind of bacteriophage containing α-carbonyl carboxylic acid configurayion and acetylacetone contains β-diketonate configurayion. They are the ideal ligands for Tb³⁺ and Eu³⁺. The fluorescence spectra of Tb³⁺ and Eu³⁺ complexes showed that the ligands were suitable for efficient energy transfer from ligands to the Tb³⁺ or Eu³⁺ ion with a high fluorescence quantum yield， large stoke shift， narrow emission bonds and large fluorescence lifetime. So the complexes were the new kind of solid fluorescence materials. Moreover， the mechanisms of the fluorescence of Tb³⁺ (Eu³⁺)-ciprofloxacina-acetylacetone ternary solid complex were investigated.
