Synthesis, structure and luminescence of novel 1D chain coordination polymers [Ln(isophth)(Hisophth)(H2O)4·4H2O]n (Ln=Sm, Dy)

Structure and luminescence studies of tris(nitrato-O,O′)bis(2,2′-bipyridyl-N,N′)dysprosium(III) complex

“…The efficient non-radiative deactivations of the O-H and C-H groups participate via vibrionic coupling with the vibrational state of the O-H and C-H oscillator [18,19]. Similar observation was noted for the [Dy(PIC) 3 [21]. Nevertheless, all the emission intensities in the [Dy(bipy) 2 (NO 3 ) 3 ] complex was lower than that found in its oxide and salt because the intramolecular energy transfer did not take place.…”

Synthesis, Thermal, Structural Analyses, and Photoluminescent Properties of a New Family of Malonate-Containing Lanthanide(III) Coordination Polymers

“…Lanthanide(III) ions are hard Lewis acids and prefer to combine with hard Lewis bases such as oxygen donors (Bünzli, 2014). On the basis of this fact, carboxylate ligands have been widely applied for the preparation of lanthanide coordination polymers (Hansson, 1973a,b; Wenmei et al, 1992; Marrot and Trombe, 1994; Benmerad et al, 2000; Hernández-Molina et al, 2000, 2002, 2003; Doreswamy et al, 2003, 2005; Thirumurugan and Natarajan, 2004; Cui et al, 2005; Yan et al, 2005; Cañadillas-Delgado et al, 2006; Deacon et al, 2006; Rahahlia et al, 2007; Zhang et al, 2007; Fang et al, 2008; Wang et al, 2009; Chrysomallidou et al, 2010; Silva et al, 2010; Jin et al, 2012; Seidel et al, 2012; Sharif et al, 2012; Calahorro et al, 2013; Tian et al, 2013; Bünzli, 2014; Delgado et al, 2016; Li et al, 2017). The flexible aliphatic dicarboxylates (e.g., malonate and succinate) are more fascinating than the rigid mono or aromatic carboxylates due to many possible conformations (Cui et al, 2005; Rahahlia et al, 2007; Wang et al, 2009; Delgado et al, 2016).…”

A new family of luminescent lanthanide based coordination polymers

“…We describe here a new family of isostructural lanthanidecontaining coordination polymers of general formula Ln 2 (OH) (C 8 To the best of our knowledge, five other families of coordination polymers involving rare earth ions and isophtalate ions have already been reported. Most of them have been obtained by hydrothermal methods [4][5][6][7][8]. The compounds described here have been obtained with a high yield by precipitation in water at room temperature.…”
