Abstract

Effects of ligand expansion on the size, morphology and loading capacity of tetrazole-based metal–organic microcapsules.

High performance of ultrasonic-assisted synthesis of two spherical polymers for enantioselective catalysis

“…All this while, SEM and TEM images of the synthesized CMNPs/1,4-Zbtbs by using ultrasonic irradiation revealed that CMNPs encapsulation was successfully done in very short time, which agrees well with our previous studies (Fig. 3 and S1 ) [43] , [44] , [45] . In addition, vibrating-sample magnetometer (VSM) was employed for investigation of magnetic properties of CMNPs/1,4-Zbtb composite.…”

“…So, our optimized catalyst was CMNPs/1,4-Zbtb and specific characterization about it was carried out. It should also be noted that due to the high structural similarities of the two ICPs, almost identical results in early characterization are not unexpected, although full characterization about Fe 3 O 4 /1,3-Zbtb was carried out in our previous work [43] , [44] , [45] . Powder x-ray diffraction (PXRD) pattern was used first as direct evidence to confirm the formation of CMNPs/1,4-Zbtb.…”

“…Energy disperse spectroscopy (EDS) [44] as another confirmatory analysis proved the existence of magnetic particles in hollow spherical capsules. In addition, this composite showed high stability in common solvents that PXRD patterns proved (CICP is insoluble in different organic solvents and water) ( Fig.…”

“…In our previous work, we reported two strong tetrazolyl infinite coordination polymers by using 1,3-btmbenzene and 1,4-btmbenzene ( Fig. 1 ) with hollow sphere morphology through three methods including solvothermal, ultrasonic irradiation, and mechanical stirring [43] , [44] , [45] . Herein, for the first time, we prepared two chiromagnetic nanoparticles/polymer composites (CMNPs/Zbtb) with the assistance of ultrasonic irradiation.…”

Syntheses and Characterization of Tetrazolate-Based Lanthanide Compounds and Selective Crystallization Separation of Neodymium and Dysprosium

“…Tetrazolate-derived ligands represent one of the most complex nitrogen-rich ligand classes with regard to their coordination ability and charge flexibility, which leads to a variety of coordination modes. − Herein, as shown in Figure , Na 2 (dtp)·2H 2 O (H 2 dtp = 2,3-di-1 H -tetrazol-5-ylpyrazine) and Na­(H 2 ibt)·3H 2 O [H 3 ibt = 4,5-bis­(tetrazol-5-yl)­imidazole] are chosen to synthesize lanthanide compounds and further used for lanthanide separation due to their facile synthesis, stability and safety, , wide diversity of potential coordination modes (the details are shown in Scheme S1), and high solubility in water. Lanthanide compounds containing anions of the tetrazole-containing ligands, Na 2 (dtp)·2H 2 O and Na­(H 2 ibt)·3H 2 O, have been synthesized by salt metathesis (Scheme ).…”
