  β-Cyclodextrin inclusion of europium(III) tris(β-diketonate)-bipyridine

  摘要：

  The adduct Eu(NTA)(3) center dot bipy was prepared by the reaction of Eu(NTA)(3) center dot 2H(2)O with 2,2 '-bipyridine in a 1:1 ratio in chloroform [NTA = 1-(2-naphthoyl)-3,3,3-trifluoroacetonate]. Recrystallization of the complex from a chloroform/diethyl ether solvent mixture gave crystals suitable for X-ray diffraction. The Structure contained chloroform Molecules in partially occupied sites and was found to be different from the two forms previously reported for the same adduct (one unsolvated and the other containing isopropanol molecules). A single eight-coordinate geometry Was found for Eu(NTA)3 center dot bipy center dot 0.44CHCl(3), corresponding to a distorted square antiprism, with the bidentate ligands spanning opposite sides of the 'square' faces. A 2:1 (host-to-guest) inclusion compound comprising beta-cyclo-dextrin (CD) and Eu(NTA)(3) center dot bipy was obtained by co-precipitation from a mixed water/ethyl acetate solvent mixture. The formation of a true inclusion complex was supported by powder XRD, thermogravimetric analysis and C-13 CP MAS NMR spectroscopy. Photoluminescence spectroscopy indicated the presence of only one low-symmetry environment for the Eu3+ cations in non-included Eu(NTA)(3) center dot bipy and the inclusion compound. However, upon encapsulation of the complex in beta-CD, some of the Eu3+ intra-4f(6) D-5(0) -> F-7(0-4) lines shifted in energy, and the number of Stark components for the D-5(0) -> F-7(1 2) transitions increased, indicating a lowering of the symmetry of the Eu3+ local coordination environment. The room temperature excitation spectrum of the inclusion compound revealed an enhancement of the Eu3+ sensitized process as a result of encapsulation of the Eu(NTA)(3) center dot bipy molecules.

  photoluminescence performance of a series of heteroleptic europium complexes with fluorinated chromophoric ligand and 2,2′-bipyridine or their derivatives as ancillary ligand are reported here. The structure of the synthesized complexes was analyzed by various spectroscopic techniques. The photoluminescence emission spectra of complexes show the existence of characteristic peaks corresponding to Eu3+

  The title compound (conveniently abbreviated Eu(TAN)(3).dipy) has been crystallized from a chloroform/2-propanol solvent mixture to give two different forms. These have been characterized by luminescence spectroscopy and by X-ray diffraction. The two forms have different coordination polyhedra which means that they are structural isomers. One of them is best described as bicapped trigonal prismatic and the other, which contains two slightly different molecules, as square antiprismatic. (C) 1998 Elsevier Science S.A.
