Three novel isostructural lanthanide(III) coordination
polymers
(LnCPs), {[Ln3(bidc)4(phen)2(NO3)]·2H2O}n (Ln
= Gd (1), Eu (2), Tb (3); H2bidc = benzimidazole-5,6-dicarboxylic acid, and phen = 1,10-phenanthroline),
were synthesized via hydrothermal reaction and characterized. The
complexes crystallize in the chiral space group P212121. They possess 1D structures
based on lanthanide trinuclear clusters containing Ln(1)O9, Ln(2)O6N2, and Ln(3)O6N2 polyhedra by bidc linkers, and phen and nitrate act as terminal
ligands. The bidc and phen ligands provide efficient energy transfer
for the sensitization of Eu(III) and Tb(III) complexes. The complexes 2 and 3 emit red and green light, respectively.
Lifetimes and quantum yields of luminescence are 0.86 ms and 13.20%
for 2 and 0.32 ms and 2.08% for 3. Tuning
of white-light emission by adjusting the doping concentration of Eu(III)
and Tb(III) ions in the Gd(III) complex was achieved.
