“…The metallopolymer, F1 containing a tetramethyldisiloxane moiety and trinuclear cobalt-aldoximate blocks was prepared by a complexation reaction between 1,3bis(carboxypropyl)tetramethyldisiloxane and the corresponding metal oximates, adopting a procedure described in the literature [5].…”

Three different small molecule or polymeric well-determined complex structures containing siloxane moieties and 3d metals were incorporated into a polymeric matrix based on a polydimethylsiloxane of low molecular weight. After the incorporation of the complex, matrix crosslinking was performed with tetraethylorthosilicate, resulting in free-standing films. The films were investigated by scanning and transmission electron microscopy (SEM, TEM), dynamic vapour sorption (DVS) analysis, stress–strain measurements and dielectric spectroscopy. The presence of the siloxane moiety in the ligand (by its surface effect) improves the compatibility between the metal complex and the silicone matrix, which ensures good mechanical properties. Thus, modulus values between 0.10 and 0.50 MPa and elongations of 210–380% were obtained. Depending on the metal type and the complexation pattern, an increasing of the dielectric constant value up to 4.6 as compared with a value of 2.5 for the silicone matrix was obtained. The samples showed good electromechanical actuation behaviour even at small voltages.

“…Herein, we report on the synthesis, structural characterization, and physical properties of nine new coordination polymers, including the first oxime-based MOFs, by the use of a 2-pyridyl oxime (pyridine-2 amidoxime, H 2 pyaox, and 2-methyl pyridyl ketoxime, Hmpko) in combination with 1,2,4,5-benzene tetracarboxylic acid (pyromellitic acid), H 4 pma ( Scheme 1 ); the latter has been employed in the field of MOFs [ 96 , 97 , 98 , 99 , 100 , 101 , 102 , 103 , 104 ], but its combination with an oximic ligand is unexplored. The 3D MOF [Cu 4 (OH) 2 (pma)(mpko) 2 ] n ( 9 ) displays selectivity for Fe 3+ adsorption.…”

The synthesis and characterization of coordination polymers and metal–organic frameworks (MOFs) has attracted a significant interest over the last decades due to their fascinating physical properties, as well as their use in a wide range of technological, environmental, and biomedical applications. The initial use of 2-pyridyl oximic ligands such as pyridine-2 amidoxime (H2pyaox) and 2-methyl pyridyl ketoxime (Hmpko) in combination with 1,2,4,5-benzene tetracarboxylic acid (pyromellitic acid), H4pma, provided access to nine new compounds whose structures and properties are discussed in detail. Among them, [Zn2(pma)(H2pyaox)2(H2O)2]n (3) and [Cu4(OH)2(pma)(mpko)2]n (9) are the first MOFs based on a 2-pyridyl oxime with 9 possessing a novel 3,4,5,8-c net topology. [Zn2(pma)(H2pyaox)2]n (2), [Cu2(pma)(H2pyaox)2(DMF)2]n (6), and [Cu2(pma)(Hmpko)2(DMF)2]n (8) join a small family of coordination polymers containing an oximic ligand. 9 exhibits selectivity for FeIII ions adsorption, as was demonstrated by a variety of techniques including UV-vis, EDX, and magnetism. DC magnetic susceptibility studies in 9 revealed the presence of strong antiferromagnetic interactions between the metal centers, which lead to a diamagnetic ground state; it was also found that the magnetic properties of 9 are affected by the amount of the encapsulated Fe3+ ions, which is a very desirable property for the development of magnetism-based sensors.

“…More importantly coordination polymers have been applied in numerous applications, including waste water treatment [6], gas storage and separation [7,8], heterogeneous catalysis [9], non-linear optics [10] and drug delivery [11]. Polycarboxylate such as -benzenetetracarboxylic acid (H4Btec) is centro-symmetric; it is an important multidentate ligand that has multiple coordination modes [12,13]. Because of its four carboxyl groups, it can display a variety of coordination modes to afford numerous coordination polymers of 1D chains, 2D layers and 3D networks [14][15][16].…”

1,2,4,5-Benzenetetracarboxylic acid (H4Btec) is an ideal candidate for the synthesis of new coordination polymers compounds because of its four carboxyl groups bridging moieties with antimony ions having distorted coordination configuration. This work reports a new compound of coordination polymer, namely, [Sb2(C4H4O6)2(Btec)(H2O)]n, [(C4H4O6)2 = tartrate and Btec4− = 1,2,4,5-benzenetetracarboxylic anion] has been synthesized under reflux. The physical and chemical properties of coordination polymers; Sb2(C4H4O6)2(Btec)(H2O) was affirmed by scanning electron microscope, Fourier transform infrared spectroscopy, X-ray powder diffraction, thermogravimetric analyses and photoluminescence spectroscopy.
