Structure variation and luminescence of 3D, 2D and 1D lanthanide coordination polymers with 1,3-adamantanediacetic acid

Abstract We report the synthesis of 3D Ln-CPs [Tb 2 (ADA) 3 ] n ( 1a , H 2 ADA = 1,3-adamantanediacetic Acid), 2D Ln-CPs [Ln 2 (ADA) 3 (dmp) 2 ] n ·2EtOH·H 2 O, (Ln 3+  = Eu 3+ , 2a ; Gd 3+ , 2b ; Tb 3+ , 2c ; dmp = 4,7-dimethyl-1,10-phenanthroline), and 1D Ln-CPs [Ln(ADA)(HADA)(H 2 O)] n (Ln 3+  = Eu 3+ , 3a ; Gd 3+ , 3b ; Tb 3+ , 3c ), by introducing the ligand H 2 ADA. The Ln-CPs are characterized by single-crystal X-ray diffraction, PXRD, TGA, elemental analysis and FT-IR. Structure variation is analyzed and suggestions are given for obtaining different types of structures. Luminescence spectra, lifetimes and quantum yields (QYs) are investigated.
