Hysteretic Gas and Vapor Sorption in Flexible Interpenetrated Lanthanide-Based Metal?Organic Frameworks with Coordinated Molecular Gating via Reversible Single-Crystal-to-Single-Crystal Transformation for Enhanced Selectivity
A series of flexible 3-fold interpenetrated lanthanide-based metal organic frameworks (MOFs) with the formula [Ln(HL)(DMA)2]·DMA·2H2O, where Ln = La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, and Er, DMA = dimethylacetamide, and H4L = 5,5′-(2,3,5,6-tetramethyl-1,4-phenylene)bis(methylene)bis(azanediyl)diisophthalic acid, have been prepared. [Sm(HL)(DMA)2]·DMA·2H2O was studied as...

Synthesis of flame-retarding oligo(carbonate-ether) diols via double metal cyanide complex-catalyzed copolymerization of PO and CO2 using bisphenol A as a chain transfer agent
Flame-retarding oligo(carbonate-ether) diols were successfully prepared with considerable efficiency by copolymerization of propylene oxide (PO) and carbon dioxide (CO2) using a Zn3[Co(CN)6]2-based double metal cyanide complex (DMC) in the presence of bisphenol A (BPA) as a chain transfer agent (CTA). The effects of molar ratio of PO to BPA, temperature, pressure and reaction time on the copolym...

Carbon Dioxide/Epoxide Copolymerization via a Nanosized Zinc–Cobalt (III) Double Metal Cyanide Complex: Substituent Effects of Epoxides on Polycarbonate Selectivity, Regioselectivity and Glass Transition Temperatures
In this study, we describe the substituent effect of epoxides on CO2/epoxide copolymerization catalyzed by a nanosized zinc?cobalt(III) double metal cyanide complex [Zn?Co(III) DMCC]. The Zn?Co(III) DMCC catalyzed the
copolymerization of CO2 with 11 epoxides with alkyl or aryl groups at 50?60 °C within 15 h. The reaction afforded various CO2/epoxide copolymers with high epoxide&nbs...

Selective production of poly(carbonate-co-ether) over cyclic carbonate for epichlorohydrin and CO2 copolymerization via heterogeneous catalysis of Zn-Co (III) double metal cyanide complex
Epichlorohydrin (ECH), as a cheap raw chemical material, is an ideal monomer for copolymerization with CO2 to produce biodegradable polycarbonates. This work describes the selective ECH-CO2 copolymerization via heterogeneous catalysis of nanolamellar zinc-cobalt double metal cyanide complex (Zn-Co (III) DMCC), affording a poly(carbonate-co-ether) with carbonate content up to 70.7%. Remarkably, t...

表面接枝聚电解质溶胀断Metal-S键的机理研究
关键字：表面引发聚合反应，石英晶体微天平，“固化水层”模型，聚电解质，断键
在多数情况下通过共价键固定在材料表面的高分子链（表面接枝高分子）是能够稳定地存在。最近，我们发现通过Metal-S键固定在金表面的聚电解质膜可以通过加入磷酸盐缓冲溶液使Metal-S键断裂，进而使膜从表面脱附。
