抄録: Luminescent Eu-III coordination polymers with rigid triangular spacer ligands are reported. The Eu-III coordination polymer, [Eu-3(hfa)(9)(tppb)(2)](n) (hfa: hexafluoroacetylacetonate, tppb: tris(4-diphenylphosphorylphenyl) benzene), shows high thermo-stability (decomposition temperature= 354 degrees C) and photoluminescence quantum yield (Phi(4f-4f)= 82%, photosensitized energy transfer efficiency= 78%). The tribolumines-cence efficiency of Eu-III coordination polymer with triangular spacers under laser pulse irradiation (Nd:YAG, lambda= 1064 nm, pulse width= 5 ns, pulse energy= 0.1 mJ) is calculated to be 49%. Characteristic triangular structure, high emission quantum yield, effective photosensitized energy transfer, and remarkable triboluminescence properties of Eu-III coordination polymers are demonstrated for the first time.
