Increasing the CO2/N2 Selectivity with a Higher Surface Density of Pyridinic Lewis Basic Sites in Porous Carbon Derived from a Pyridyl-Ligand-Based Metal–Organic Framework
The development of functional porous carbon with high CO2/N2 selectivity is of great importance for CO2 capture. In this paper, a type of porous carbon with doped pyridinic sites (termed MOFC) was prepared from the carbonization of a pyridyl-ligand based MOF. Four MOFCs derived from different carbonizing temperatures were prepared. Structural studies revealed high contents of pyridinic-N groups an...

[Macromolecules] Bottle-Brush Brushes: Surface-Initiated Rare Earth Metal Mediated Group Transfer Polymerization from a Poly(3-((2,6-dimethylpyridin-4-yl)oxy)propyl methacrylate) Backbone
A general and efficient method for the preparation of bottle-brush brushes is presented via the combination of self-initiated photografting and photopolymerization (SIPGP) and rare earth metal mediated group transfer polymerization (REM-GTP). This strategy involves the creation of poly(3-((2,6-dimethylpyridin-4-yl)oxy)propyl methacrylate) (PDMPPMA) brushes and the successive conversion to surfac...

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...
