Doubly Interpenetrated Metal−Organic Framework of pcu Topology for Selective Separation of Propylene from Propane
53次浏览
Ting Liu, Hui Cui, Xin Zhang,* Zhi-Yin Zhang, Rui-Biao Lin, Bin Liang, Jian Zhang, Dan Li,* and Banglin Chen*ABSTRACT: Adsorptive separation is an appealing alternative technology to reduce the high energy and capital cost of the distillation separation of propylene/propane; however, it is very challenging to realize. A new flexible metal−organic framework (MOF) material [Zn2(BDC-Cl)2(Py2TTz)] with a doubly interpenetrated pillared paddle wheel structure of pcu (primitive cubic) topology has bee

Chiral ligand exchange capillary electrochromatography with dual ligands for enantioseparation of D,L-amino acids
52次浏览
Abstract:Utilizing block copolymers as coatings, a protocol of chiral ligand exchange capillary electrochromatography (CLE-CEC) protocol was designed and developed with dual ligands for D,L-amino acids enantioseparation. Four block copolymers incluing poly maleic anhydride-co-styrene-co-N-methacryloyl-L-histidine methyl ester [P(MAn-St-MAH)], poly maleic anhydride-co-styrene-co-N-methacryloyl-L-lysine methyl ester [P(MAn-St-MAL)], poly maleic anhydride-co-styrene-co-N-methacryloyl-L-phenylalanin

Carbonyl-based polyimide and polyquinoneimide for potassium-ion batteries
46次浏览
Abstract: Although potassium-ion batteries (KIBs) are potentially alternative energy storage systems to lithium-ion batteries (LIBs), only few organic materials can be used as candidate electrodes for KIBs. Herein, we synthesized a class of carbonyl-based organic polymers including two 1D linear polymers, namely polyimide (PI) and polyquinoneimide (PQI), and a 2D conjugated microporous polymer (PI-CMP) as stable organic cathode materials for KIBs. The investigation of their electrochemical perfo

Cage-Interconnected Metal−Organic Framework with Tailored Apertures for Efficient C2H6/C2H4 Separation under Humid Conditions
38次浏览
Abstract:Metal-organic frameworks (MOFs) with open metal sites (OMSs) have been shown to preferentially adsorb unsaturated hydrocarbons such as C2H4due to the formation of π-complexation. However, the adsorption capacity and selectivity might well be dampened under humid conditions because OMSs could be easily poisoned in the presence of water vapor. C2H6-selective adsorbents with less hydrophilic environments, on the other hand, not only could effectively minimize the impact of humidity on sepa

Fine-Tuning Apertures of Metal−Organic Cages: Encapsulation of Carbon Dioxide in Solution and Solid State
36次浏览
Abstract: Metal-organic cages are potential artificial models for mimicking biological functions due to their capability of selective encapsulation for certain guest molecules. In this work, we designed and synthesized a series of rhombic dodecahedral Ni-imidazolate cages (Ni14L24) with precisely controlled aperture for CO2encapsulation. The aperture of the cages can be tuned by the strategies of ligand decoration and metal-ion hybridization. Similar to the breathing function of alveoli, CO2pass

Trigonal Prismatic Cu6L3 Coordination Cage: Encapsulation of Aromatic Molecules and Tuned Photoluminescence
32次浏览
Abstract: A trigonal prismatic Cu6L3coordination cage has been assembled from Cu(I) and semi-rigid bipyrazolyl ligand. The X-ray crystallography demonstrates that the cage has a cavity and can encapsulate the toluene as a guest, exhibiting thermochromism phenomenon. Empty cage can be obtained by expulsion of the guest through single crystal to single crystal transformation. After removed the guest, the empty cage shows a blue-shifted emission (580 nm), in comparison to its parent cage (615 nm).
