Microwave-assisted synthesis of lanthanide 2,6-naphthalenedicarboxylates: Thermal, luminescent and sorption characterization

Structural and Thermal Investigations of Co(II) and Ni(II) Coordination Polymers Based on biphenyl-4,4′-dioxydiacetate Linker

“…The present study is a continuation of our research on coordination polymers assembled from aromatic polycarboxylic acids [33][34][35][36][37][38]. Recently, our attention has focused on probing biphenyl-4,4'-dioxydiacetic acid (H 2 L) (Scheme 1) as a flexible linker toward lanthanides and alkali metals [39,40].…”

“…The molecules of water, formic acid, and carbon dioxide were released at first (Figure 7). The FTIR spectra showed weak broad bands in the wavenumber ranges of 4000-3400 and 1900-1300 cm −1 as a result of stretching and deformation vibrations of OH groups from evolved water molecules [33][34][35][36][37][38]. In the range of 3150-2600 cm −1 , there was a broad band with the maxima at 2931 and 2854 cm −1 due to the stretching CH vibrations from evolved formic acid [67].…”

“…Materials 2021, 14, x FOR PEER REVIEW 2 of 15 the polycarboxylic acid linkers that comprise a rigid biphenyl, naphthalene, pyrene, or pyrazine moiety, diverse flexible multicarboxylate linkers have gained particular attention for generating novel metal-organic architectures [28][29][30][31][32]. The present study is a continuation of our research on coordination polymers assembled from aromatic polycarboxylic acids [33][34][35][36][37][38].

Lanthanide metal–organic frameworks: Structural, thermal and sorption properties

“…Moreover, the spectra show two bands characteristic of DMF molecules. The bands at 3066 and 2928 cm À1 from the stretching vibrations of CH 3 groups as well as bands at 1667 and 1643 cm À1 were assigned to the stretching vibrations of free and coordinated carbonyl groups from the DMF (Lyszczek and Lipke, 2013).…”

“…The lanthanide MOFs with benzene polycarboxylic acids have been investigated by our group for many years. The whole series of lanthanide complexes with rigid (Lyszczek, 2007;Lyszczek and Lipke, 2013;Lyszczek et al, 2011) or more flexible benzene polycarboxylic acids (Lyszczek and Mazur, 2012, Lyszczek et al, 2016a, 2015 were synthesized and investigated. As the continuation of our research on lanthanide MOFs, neodymium(III) and erbium(III) complexes with 1,3,5-benzenetricarboxylic acid were prepared by the solvothermal method using dimethylformamide (DMF) as a solvent (Lyszczek et al, 2016b).…”
