Description Eu(NO3)3.5H2O and EuCl3.6H2O were allowed to react with bis(diphenylphosphino)alkane dioxides Ph2P(O)(CH2)nP(O)Ph2 (n?=?2, 4, 6) to obtain polymeric and binuclear complexes. The prepared compounds were structurally characterized by X-ray diffraction. Luminescence measurements (emission and excitation spectra, quantum yields, lifetimes) were compared with crystallographic data in order to find a relationship between luminescent properties of the Eu(III) complexes and their structures. The Eu(III) polymers, especially {[Eu(dpphO2)2Cl2]+Cl-}n, have shown extremely long luminescence lifetimes, up to 3.73ms, as a result of a highly protecting hydrophobic shield.
