- Abstract
The semirigid exo-bidentate ligand 1, 4-bis{[(2′-picolylaminoformyl)phenoxyl]methyl}-2, 5-bismethylbenzene (L) was designed, synthesized, and used as building blocks for constructing luminescent lanthanide polymers. Two new lanthanide coordination polymers were characterized by elemental analysis, X-ray diffraction analysis, and IR spectroscopy. The coordination polymers exhibit the metal-to-ligand molar ratio of 1:1 and the semirigid exo-bidentate ligand bridges lanthanide nitrates forming a zigzag chain, which further interconnected to three dimensional supramolecular structure in aid of cooperative C-H ···O hydrogen bonds. The luminescence properties of the europium(III) complex are discussed in detail.
