A highly robust heterometallic Tb^III/Ni^II–organic framework for C₂ hydrocarbon separation and capture

Abstract

The exquisite combination of hetreometallic [TbIIINiII(COO)3(H2O)] clusters with a designed hexatopic ligand generates one highly robust three-dimensional heterometallic TbIII/NiII–organic framework material.

Nanochannel-based {BaZn}–organic framework for catalytic activity on the cycloaddition reaction of epoxides with CO2 and deacetalization-Knoevenagel condensation

“…In addition, NUC-51 has a common feature with previously reported {ZnCa}-TDP and M II Ln III -TDP (M II Ln III , M = Mn, Co, Ni, Zn; Ln = rare earth cations) heterometallic MOFs, [24][25][26][27] in which the 3d cation of Zn(II) displays a tetra-coordinated mode, which should be attributed to the synergetic coordination effect between the heterometallic ions and the structure-oriented polycarboxylic ligand of H 6 TDP. Meanwhile, judged by the structures of achieved heterometallic MOFs, the main structure-oriented factor of H 6 TDP should be ascribed to the fact that TDP 6− owns multiple αand γ-carboxyl groups with chelating tendency, especially the ones affected by the electron density of N pyridine atoms.…”

“…Nevertheless, with the employment of 1.0 mol% NUC-51a and 2.5 mol% n-Bu 4 NBr, the conversion of styrene oxide increased significantly with the final rate of 43.3%, which should be ascribed to the fact that n-Bu 4 NBr as one kind of recognized nucleophilic co-catalyst played an important role in the multistage reaction system (entry 4). [24][25][26][27] Then, based on the employment of NUC-51a and n-Bu 4 NBr, temperature verification tests were carried out. Just as shown in entries 5-7, along with reaction temperature ranging from 35 °C to 55 °C with the interval of 10 °C, the conversion rate of styrene oxide ascended from 58.3% to 92.2%, which proved that the reaction temperature had a significant effect on the reaction rate.…”

“…[21][22][23] We have recently reported a series of heterometallic MOFs with excellent physicochemical properties including honeycomb channels, large specific surface area, coexisting Lewis acid-base sites, and high chemical stability. [24][25][26][27] However, the inherent laws regarding the arrangement and coordination number of the involved metal ions in cluster SBUs are still uncovered.…”

Robust Heterometallic TbIII/MnII–Organic Framework for CO2/CH4 Separation and I2 Adsorption

“…The detailed synthetic routes for H 6 TDP was reported in our recent studies. 28 The infrared spectrum (IR) in the range of 500−4000 cm −1 was measured on Nicolet 740 FTIR spectrometer. The element analysis (C, H, and N) was fulfilled on the EA 1110 element analyzer of CE instrument.…”

Design, Synthesis and Photoluminescence Sensing Property of a Ni‐Organic Material Achieved from 2,6‐Di(1H‐imidazol‐1‐yl) Naphthalene and Carboxylic Acid Ligands

“…But acetone is toxic, especially on the nervous system has an anesthetic effect, and the human mucosa has a stimulating effect, can inhibit breathing, cause breathing difficulties. Therefore, it is urgent to seek an excellent analytical method for detecting acetone [12–15] . Compared with electrochemical method, atomic absorption spectrometry and spectrophotometry, luminescence sensing has the advantages of simple preparation, convenient operation, low cost, clear and stable luminescence signal, good selectivity and sensitivity [16] …”
