(4,4)-and(6,3)-2-D luminescent lanthanide(III)metal-organic frameworks constructed from tetrafluorosuccinate and 1,10-phenanthroline

摘要

Two new coordination polymers[Eu2(TFSA)3(phen)2]_n(1)and[Tb2(TFSA)3(phen)4(H2O)2]_n(2)(TFSA=tetrafluorosuccinate,phen=1,10-phenanthroline)have been synthesized and structurally characterized.The 1 has a 2-D grid-like network structure with(4,4)topology and the 2 has a 2-D honeycomb-like network structure with(6,3)topology.The two complexes exhibit strong photoluminescence of the Eu(III)for 1 and Tb(III)for 2,respectively.
