Study On Iuminescent Eu(Ⅲ),Tb(Ⅲ)Macromolecular Complexes And BODIPY Dyes

The study of two kinds of fluorescent materials was carried out in this thesis, which mainly contains the synthesis, characterization and fluorescence properties of europium(Eu), terbium(Tb) macromolecular complexes, the application of linear polymeric vinyl ligands in the metal enrichment and separation, and the preparation and the application of sensing anions of BODIPY dyes. The paper consists of six parts as follows:1. A brief review of the study progress and application of fluorescent lanthanides macromolecular complexes (LnMC) and BODIPY dyes has been given.2. A series of poly styrene and acrylic acid ligands (L1, L2, L3) and corresponding lanthanides macromolecular complexes (LnL13, LnL23, LnL33, Ln=Eu and Tb, Fig.1) were synthesized, then the study of structure, characterization and fluorescence properties were carried out.3. Copolymers of Poly(styrene-co-maleic anhydride) with8-Aminoquinoline (L4) and Poly(styrene-co-maleic anhydride) with p-aminophenolwith (L5) as well as their corresponding lanthanide macromolecular complexes LnL43and LnL53(Ln=Eu and Tb, Figs.2and3) were synthesized and characterized, and their fluorescence properties were studied detailed. 4. We use the copolymer of styrene-co-maleic anhydride to separate Pt2+and Zn2+in the solution, characterized SMA and Pb-SMA complexes, and the adsorption behavior of SMA towards Pb2+, Zn2+were also studied. 5. BODIPY derivative1(Fig.5) containing aminocoumarin as a recognition subunit was synthesized, and its selective recognition reaction and mechanism to F" and H2PO4-anions were studied.6. The selective recognition and sensing of BODIPY derivative2(Fig.6) with phenylamine acting as a recognition subunit to fluoride anion were studied. The results show that these synthesized lanthanide macromolecular complexes can be used to prepare fluorescent materials; the macromolecular guide can be used in the metal enrichment and separation. BODIPY fluorescence dye are easily soluble in most organic solvents, and they have strong fluorescence; some BODIPY dyes containing different recognition subunits can be applied to selectively recognize and sense different anions.
