摘要：
Four new complexes [Ln(pfaa)(3)(H2O)(2)](n) (Ln = Eu (1), Tb (2)) and [Ln(2)Cd(2)(pfaa)(10) (phen)2(EtOH)(2)]center dot 2MeCN (Ln = Eu (3), Tb (4), phen = 1,10-phenanthroline) based on pentaphorphenylacetic acid (Hpfaa) have been prepared and completely investigated. The structures of compounds 1 and 3 were studied by single crystal X-ray diffraction analysis: the isostructural complexes 1 and 2 represent 1D coordination polymer, while the isostructural complexes 3 and 4 are molecular compounds. Complexes 1-4 show strong lanthanide-centred luminescence, since the introduction of phenanthroline leads to a significant increase in the observed lifetime (tau(obs)) and photoluminescent quantum yield.
