摘要:
                                A pentadentate ligand L (2-(2-((bis(pyridin-2-ylmethyl)amino)methyl)phenoxy) -N,N-diphenylacetamide) was self-assembled with Eu (NO3)(3) or Zn (NO3)(2)/Eu (NO3)(3) to give homometallic complex ([EuL(NO3)(3)], 1) or ion associating complex ([ZnL(NO3)](2)center dot[Eu(NO3)(5)]center dot CH3CN, 2). respectively. The photoluminescent behavior and energy transfer process were studied in the two complexes by excitation in different ways, in which 2 shows Forster energy transfer mechanism. (C) 2012 Elsevier B.V.
