英文摘要	two europium trifluoroacetate complexes, eu(cf3coo)(3)center dot phen (1) and eu(cf3coo)(3)center dot bpy (2) (where phen=1,10-phenanthroline, bpy=2,2'-bipyridine), were synthesized and characterized by elemental analysis, fourier transform infrared spectroscopy (ft-ir), photoluminescence (pl) spectroscopy and thermogravimetric analysis (ta). single-crystal x-ray structure has been determined for the complex [eu-2(cf3coo)(6)center dot(phen)(3)center dot(h2o)(2)]center dot etoh. the crystal structure of [eu-2(cf3coo)(6)center dot(phen)(3)center dot(h2o)(2)]center dot etoh shows that two different coordination styles with europium ions coexist in the same crystal and have entirely different coordination geometries and numbers. this crystal can be considered as an 1 : 1 adduct of [eu(cf3coo)(3)center dot(phen)(2)center dot h2o]center dot etoh (9-coordination part) and eu(cf3coo)(3)center dot phen center dot h2o (8-coordination part). the excitation spectra of the two complexes demonstrate that the energy collected by "antenna ligands" is transferred to eu3+ ions efficiently. the room-temperature pl spectra of the complexes are composed of the typical eu3+ ions red emission, due to transitions between d-5(0) -> f-7(j(j=0 -> 4)). the lifetimes of d-5(0) of eu3+ in the complexes were examined using time-resolved spectroscopic analysis, and the lifetime values of eu(cf3coo)(3)center dot phen and eu(cf3coo)(3)center dot bpy were fitting with bi-exponential (2987 and 353 mu s) and monoexponential (3191 mu s) curves, respectively. in order to elucidate the energy transfer process of the europium complexes, the energy levels of the relevant electronic states had been estimated. the thermal analyses indicate that they are all quite stable to heat.
