“…We should note here that blocks with either 2,2′-bipyridyl (bpy) or 1,10-phenantroline ligands are well known in the chemistry of lanthanide(III) complexes (69 unique hits in CSDB ver. 5.42 (November 2020) [ 42 ]) with monocarboxylate ligands, such as acetate, benzoate and their derivatives [ 43 , 44 , 45 , 46 , 47 ], but no examples for Y 3+ have been reported so far. Additionally, 1 , as well as all other isostructural compounds obtained in this work, represents the first example of extended coordination polymer structures based on such a {M 2 L 2 (NO 3 ) 2 (OOCR) 4 } building unit (where M = any metal cation, L = any chelate N-donor ligand).…”

Three isostructural metal–organic frameworks ([Ln2(phen)2(NO3)2(chdc)2]·2DMF (Ln3+ = Y3+ for 1, Eu3+ for 2 or Tb3+ for 3; phen = 1,10-phenanthroline; H2chdc = trans-1,4-cyclohexanedicarboxylic acid) were synthesized and characterized. The compounds are based on a binuclear block {M2(phen)2(NO3)2(OOCR)4} assembled into a two-dime nsional square-grid network containing tetragonal channels with 26% total solvent-accessible volume. Yttrium (1)-, europium (2)- and terbium (3)-based structures emit in the blue, red and green regions, respectively, representing the basic colors of the standard RGB matrix. A doping of Eu3+ and/or Tb3+ centers into the Y3+-based phase led to mixed-metal compositions with tunable emission color and high quantum yields (QY) up to 84%. The bright luminescence of a suspension of microcrystalline 3 in DMF (QY = 78%) is effectively quenched by diluted cinnamaldehyde (cinnamal) solutions at millimolar concentrations, suggesting a convenient and analytically viable sensing method for this important chemical.

“…Rare earth elements (REEs) are widely distributed throughout the earth's crust in low concentrations. As it is known, lanthanide complexes have attracted widespread interest due to the wide variety of potential applications in magnetic materials, catalysts, photoelectric conversion material, and so on . Comparatively less is known about the biological properties of lanthanide complexes .…”

Two aliphatic ether Schiff base lanthanide complexes (Ln = Eu, Ce) with bis(3‐methoxysalicylidene)‐3‐oxapentane‐1,5‐diamine (Bod), were synthesized and characterized by physicochemical and spectroscopic methods. [Eu(Bod)(NO3)3] (1) is a discrete mononuclear species and [Ce(Bod)(NO3)3DMF]∞ (2) exhibits an inorganic coordination polymer. In the two complexes, the metal ions both are ten‐coordinated and the geometric structure around the LnIII atom can be described as distorted hexadecahedron. Under excitation at room temperature, the red shift in the fluorescence band of the ligand in the complexes compared with that of the free ligand can be attributed to coordination of the rare earth ions to the ligand. Moreover, the antioxidant activities of the two complexes were investigated. The results demonstrated that the complexes have better scavenging activity than both the ligand and the usual antioxidants on the hydroxyl and superoxide radicals.
