The stability constants of ML binary system and MLL′(M=La^3+~Yb^3+, Y^3+ and Ca^2+; L=DLmalic aicd, L′=Lhydroxyproline) ternary system were determined by pHpotentiometric method under the simulating physiological condition(37 ℃, I=015 mol/L NaCl). The complex species MpLqL′rHs(abbr as pqrs) in the sytems were ascertained by program COMPLEX. The results show that there are three species(1101, 1100 and 1200) in ML binary system and one species(1010) in ML′ binary system. In addition to the above four species, a new species, 1112 was found in the MLL′-ternary system, which is the only species of mixed ligands. Rare earth ions form more stable complexes than calcium ion does and the stability differences between their complexes in the ternary system are less than that in the binary system. The distributions of all the species in LaLL′-ternary system vs pH are discussed. 展开更多

In order to study the luminescent properties of ternary rare earth complexes with fl-diketone ligand, three new β-diketone ligands, 1-phenyl-3-(p-phenylethynylphenyl)-1,3-propanedione(HPPP), 1-(2-thienyl)-3-(p-phenylethynylphenyl)-1,3-propanedione (HTPP) and 1-(2-furyl)-3-(p-phenylethynylphenyl)-1,3-propanedione (HFPP), were synthesized by Sonogashira coupling reaction and Claisen condensation. Three new ternary rare earth complexes, TbL3phen (L = PPP, TPP, or FPP), were synthesized by the reaction of rare earth chloride TbCl3,1,10-phenanthroline (phen) with HPPP, HTPP, or HFPP respectively, in alcohol solution. The compositions were characterized by means of elemental analysis, chemical analysis, and IR spectra. Luminescent properties of the three new complexes have been studied. The results show that the ternary Yb(Ⅲ) complexes only emit the weak fluorescence of the Tb(Ⅲ) ion, which reveals the triplet state energy of the ligands does not match well with the excited state vibrating energy of Tb^3+ ion. 展开更多

Three new reactive ternary terbium complexes were synthesized with the first ligand of thenoyltri-(fluoroacetone) and the reactive secondary ligand such as maleic anhydride, undecenoic acid, oleic acid, and characterized by means of elemental analysis, ethylenediamine tetraacetic acid titrimetric method, Fourier transform infrared and ultraviolet spectroscopies. And the luminescent properties of the ternary terbium complexes were investigated. The results show that the ternary terbium complexes possess much higher luminescent intensity than the binary complex of terbium with thenoyltrifluoroacetone, and the synergy ability sequence of the three reactive ligands is as follows: undecenoic acid>oleic acid>maleic anhydride. Because the ternary terbium complexes contain reactive (ligands) that can be copolymerized with other monomers, a new way for the synthesis of the bonding-type rare earth polymer functional materials with excellent luminescent properties is provided. 展开更多

Seven ternary Eu (m) complexes were synthesized with aromatic carboxylic acid (benzoic acid, phenylacetic acid, phenylpropionic acid and cinnamic acid) as the first ligand and 1,10-phenanthro- line or 2,2'-dipyridyl as the second ligand. The ternary Eu( Ⅲ ) complexes were characterized by elemental analysis, IR and TG-DTG methods. In these complexes, the Eu (Ⅲ) ions are bonded to the oxygen atoms of carboxylate and the nitrogen atoms of neutral ligands. Four complexes whose second ligand is 1,10- phenanthrolin have fine thermal stability. Excitation and luminescence spectra of the tide complexes reveal that the fluorescence of the complexes in which 1,10- phenanthrolin as the second ligand are more intensive than those complexes in which 2, 2'-dipyridyl as the second ligand. The order of the strongest emission peak of seven ternary complexes is: Eu(β-PPA)3phen 〉 Eu(BA)3phen 〉 Eu(PLA)3phen 〉 Eu(BA)3bipy 〉 Eu ( PEA)3bipy 〉 Eu ( CA )3phen · H2O 〉 Eu ( CA )3bipy (BA : benzoic ; PEA : phenylacetic ; β-PPA : 展开更多

The compositions of the ligands and the europium (Ⅲ) ternary complexes were confirmed by elementary analysis, IR and (()~1H-NMR) spectroscopy. The UV-visible absorption spectra, thermal stability, photoluminescence spectra, quantum yield and fluorescence life time of the Eu(Ⅲ) complexes were investigated. The effect of the structure of the secondary ligand on the photoluminescence of the complexes was discussed. The results show that the synthesized Eu(Ⅲ) complexes are good red-emitiing materials for potential application in fabrication of organic electroluminescence devices. 展开更多

Under the mild condition a new ternary rare earth complex Eu ( DBM )2MA · 2H2O [ DBM: C6H5COCHCOC6H5; MA: CH2C(CH3)COO^- ] was synthesized by the reaction of EuCl3 with dibenzoylmethane and methacrylate in alcohol. A new bonded copolymer Eu(DBM)2MA-MMA was prepared by copolymerization of the Eu(DBM)2MA·2H2O complex with methyl methacrylate(MMA) monomer using AIBN as an initiator. The composition, structure and fluorescence properties of the complex and copolymer were characterized by means of elemental analysis, complex titration, IR, UV-VIS and fluorescent spectra. The thermal stability, glass temperature and average molecular weight of the copolymer Eu(DBM)2MA-MMA were determined by TG-DTA, DSC and GPC, respectively. The research results show that both of the ternary rare earth complex and the copolymer can emit strong Eu(Ⅲ) fluorescence at 613 nm. 展开更多

One ternary complex of europium with the plant growth regulator HDPHA (2-Hydroxydiphenyl acetic acid) and Phen (1,10-Phenanthroline), Eu(DPHA) 3·Phen·2H 2O, was synthesized and characterized by the elemental analysis and DTA-TG measurement. The photophysical property of the complex was investigated by means of IR spectra, Raman spectrum and laser-exited, high-resolved excitation and emission spectra as well as time-resolved luminescence spectra. The luminescence spectra reveal four Eu 3+ sites with energy difference within 25 cm -1 and local symmetries of C 1 or C 2 or C s in the complex. The energy transfer among the Eu 3+ sites is observed. The 7F J sublevel splitting of the Eu 3+ ion is discussed. 展开更多

The polymer-bound Schiff base ternary manganese complexes were characterized by means of infrared spectrometry and ICP-AES. The catalytic activities of the complexes have been studied in the aerobic epoxidation of long-chain linear aliphatic olefins. It is shown that 1-octene or 1-decene can be directly oxidized by molecular oxygen when catalyzed by PS-SalPhe-Mn-L(L=Phen, Bipy and 8HQ), and 1,2-epoxy alkane can be afforded in these reactions. 展开更多
