On the basis of 2,6-bisbenzoylactyl pyridine(L1), 2,6-bis[(3-pyrazoleyl) -5-phenyl]pyridine (L2)and2,6-bis[(3-pyrazoleyl)-3,5-bisphenyl]pyridine(L3) are synthesized. With the synthesized organic compounds as organic ligands, corresponding terbium(Ⅲ) complexes are prepared .The composition of these new compounds are confirmed by 1H-NMR, EA , IR spectrum , UV spectrum and MS .The properties of the complexes are characterized by EA,IR spectrum ,UV spectrum,TG-DTA and fluorescence spectra. Photoluminescence measurements indicate that the effective energy transfer from the organic ligand L2 to the central Tb(Ⅲ) ions occurs in the complexe, and strong and characteristic green mission appears due to the 5D4- 7F5 transitions of the 4f electrons of the central Tb(Ⅲ) ions. The fluorescence spectra shows that the fluorescence emission intensity of Tb(L2) 3·3H2O is stronger than that of Tb2(L1) 3·4H2O,but the property of TG-DTA is not so good as we expected. It cannot be the best material for fabrication of organic light-emitting devices. 展开更多

The complex[Tb_2(ClC_6H_4COO)_6(2,2'-bipy)_2]·(ClC_6H_4COOH)·(H_2O)with m-chlorobenzoic acid and 2,2'-bipy -ridine as ligands has been synthesized by means of hydrothermal way.Crystal data for this complex are as follows: monoclinic,space group P1,a=1.143 9(4) nm,6=1.211 6(4) nm,c=1.419 9(5) nm,α= 103.600(6)°,β=95.382(3)°,γ= 99.506(4)°,V=1.8684(10)nm^3,D_c=1.692 g·cm^(-3),Z=2,μ(Mo Kα)=2.236 mm^(-1),F(000)=943,final discrepancy factors R_1=0.052 0,wR_2=0.118 6.In the crystal,two neighboring Tb(Ⅲ) ions are bridged by four m-chlorobenzoic acid anions,and their end positions coordinate with one 2,2'-bipyridine molecule and one m-chlorobenzoic acid anions, respectively,giving a binuclear cage structure,of which the spacing between Tb(Ⅲ)…Tb(Ⅲ) is 0.408 1 nm.Each Tb(Ⅲ) ion coordinates with two nitrogen atoms and six oxygen atoms,giving an eight-coordinated distorted square antiprism geometry.The luminescent property of the complex is also studied. 展开更多

A terbium(Ⅲ) complex [Tb2(NO3)(DMPA)5(phen) 2] (HDMPA=homoveratric acid, C12H12O4; phen=1,10- phenanthroline), was synthesized and characterized by elemental analysis, IR and TG-DTG. Its crystal structure was determined by single crystal X-ray diffraction method. The complex, C74H71N5O23Tb2, crystallizes in the monoclinic system, space group P21/n. The emission spectrum of complex, there are four main peaks, 489, 545, 584 and 622 nm, respectively, corresponding to 5D4→7F6, 5D4→7F5, 5D4→7F4 and 5D4→7F3 transitions of Tb(Ⅲ). The intensity of 5D4→7F5 is much stronger than others. 展开更多
