Synthesis, Structure and Near Infrared Fluorescence Property of a New Nd-MOF Based on a Triangular Benzylamine Ligand

A new 3D metal-organic framework {[Nd 2 L 2 ]·2NH 2 (CH 3 ) 2 ·3H 2 O} (Nd-MOF) was successfully established via a solvothermal method with Nd 3+ ion and 5-(bis(4-carboxybenzyl)amino) - isophthalicacid (H 4 L), and has also been characterized by X-ray diffraction, powder X-ray diffraction (PXRD), IR and photoluminescence(PL)spectrum. The neodymium ions are free of coordinated solvents, and the Nd-MOF exhibits strong near-infrared (NIR) fluorescence. Besides, its NIR fluorescence property shows low temperature resistance, which is favorable for being used in the low temperature environment.
