Title: Syntheses, structures and photoluminescence of lanthanide-organic frameworks assembled from multifunctional N,O-donor ligand

Four new lanthanide complexes [Ln(O–NCP){sub 2}(NO{sub 3})]{sub n} based on multifunctional N,O-donor ligand 2-(2-carboxyphenyl)imidazo(4,5-f)-(1,10)phenanthroline (O–HNCP) and Ln(NO{sub 3}){sub 3}·6H{sub 2}O (Ln=Nd(1), La(2), Sm(3), Eu(4)) have been achieved under hydrothermal conditions and characterized by elemental analyses, infrared spectra and single crystal X-ray diffraction. Structural analyses revealed that all of these four complexes possess similar two-dimensional layer structures. In addition, thermal stability and luminescent properties of these complexes were also investigated. - Graphical abstract: A series of lanthanide(III) coordination polymers with intriguing structures based on 2-(2-carboxyphenyl)imidazo(4,5-f)-(1,10)phenanthroline ligand have been hydrothermally synthesized. The thermal stabilities and photoluminescence properties of these complexes have been investigated. - Highlights: • Four lanthanide(III) complexes have been hydrothermally synthesized. • The N,O-donor O–HNCP was used as the ligand. • TGA and PL properties of complexes 1–4 have been investigated.
