| Abstract: Two lanthanide coordination polymers, La(nbpdc)(phen)(FA) (1), Eu(nbpdc)(phen)(FA) (2) (FA=formic acid ion)based on bridging ligand 2,2'-dinitro-4,4'-biphenyldicarboxylic acid (H2nbpdc) and 1,10-Phenanthroline monohydrate (phen), have been synthesized by the hydrothermal method and characterized by IR, single-crystal X-ray structure analysis, thermogravimetric analysis, luminescent properties, circular dichroism (CD) analysis and dielectric properties. Complexes 1 and 2 exhibited a rare three-interlude 3D structure with the same topology structure of (44·62). In addition, the two complexes exhibit fluorescent emissions in the solid state at room temperature. Fluorescent analysis of complexes 1 and 2 showed an intense emission band at 606 nm (λex=495 nm) and 615.5 nm (λex=395.5 nm), respectively. Moreover, the circular dichroism analysis of complexes 1 and 2 was measured with chirality. |
