“…The rate of the degradation process for nanosized 1 was calculated according to the pseudo‐first‐order reaction kinetics equation . By plotting ln( C 0 / C ) against reaction time ( t ) we can calculate the rate of the reaction according to the linear relationship between ln( C 0 / C ) and t as presented in Figure S13: …”

“…In the last few decades considerable attention has been paid to the design and construction of new supramolecular coordination polymers (SCPs) not only for their intriguing structural motifs with unusual topologies and functional properties, but also for their various properties for application in the fields of host–guest chemistry, magnetism, gas storage, ion exchange, photocatalysis, bioinorganic chemistry, electrical conductivity, catalysis, nanosized reaction containers and so on . Compared with the traditional self‐assembly methods, use of ultrasonic irradiation has recently been considered as a facile and environmentally friendly method for the formation of nanostructured SCPs which exhibit superior properties . Although sonochemical methods have been adopted for the preparation of nanomaterials, the application of the ultrasonic method for construction of SCPs has received relatively limited attention .…”
Orange prismatic crystals of the supramolecular coordination polymer (SCP) ∞3[Cu(CN)2(Me3Sn)(Pyz)], SCP1, were synthesized using a self‐assembly method under ambient conditions. Nanosized 1 was obtained using the same molar ratio in water by ultrasonic irradiation. SCP1 was characterized using single‐crystal X‐ray diffraction, elemental analysis, thermal analysis and Fourier transform infrared spectroscopy. SCP1 and its nanosized 1 particles were also examined using powder X‐ay diffraction and scanning electron microscopy. The luminescence emission of SCP1 was studied as well as its use as a sensor for the detection of common organic solvents and metal ions. Also, the catalytic activities of nanosized 1 towards various organic dyes were investigated under ambient conditions, UV irradiation and ultrasonic irradiation. Nanosized 1 as a heterogeneous nanoparticle catalyst exhibits high catalytic activity for the degradation of eosin‐Y and acid blue dyes. The mechanism of degradation investigated using various scavenger techniques is proposed and discussed. The catalytic oxidation process is mainly caused by •OH radicals.

“…The design and construction of coordination polymers (CPs) has been one of the most active areas of material research in recent years. Being easily and efficiently synthesized from relatively simple subunits, CPs exhibit a fascinating variety of architectures and topologies and have attracted considerable interest for their potential applications (catalysis, magnetism, electric conductivity, and nonlinear optics) as functional materials [3][4][5]. Most CPs are usually made by combining a conducting organic network with an inorganic magnetic component.…”
“…There are several known complexes of H2pzdc that act as mono-, di-, or multidentates. For these reasons, H2pzdc is an important bridging ligand that is used to design CPs [29][30][31][32][33][34].…”
In this study, two new coordination polymers of Cu(II) and Cd(II) ions with pyrazine-2,3-dicarboxylic acid and 1-vinylimidazole were synthesized. The structures of these coordination polymers were characterized with elemental analysis, infrared spectroscopy, thermal analysis, powder X-ray diffraction, and magnetic susceptibility techniques. According to the results of the thermal analysis, the coordination polymers that contained water molecules decomposed below 100 °C, and the final products for both coordination polymers were the related metal oxides in an oxygen atmosphere. Powder X-ray diffraction analysis revealed that the coordination polymers were in the crystalline form. The hydrogen storage capacities and surface areas of the coordination polymers were also determined. The highest hydrogen storage capacities were measured as 296 ml/g for the Cu(II) coordination polymer and 330 ml/g for the Cd(II) coordination polymer at approximately 75 bar and 75 K.
