Highly Active Organic Lewis Pairs for the Copolymerization of Epoxides with Cyclic Anhydrides: Metal-Free Access to Well-Defined Aliphatic Polyesters
关键字：Epoxides with Cyclic Anhydrides，Metal-Free，
Polyester synthesis from the alternating copolymerization of epoxides with cyclic anhydrides via a metal-free route remains a key challenge. This work reports the development of a highly active organocatalytic route for the copolymerization of a spectrum of epoxides and cyclic anhydrides. Fully alternating polyesters were synthesized by a variety of organic Lewis acid?base pairs including organo...

Anionic Copolymerization of Carbonyl Sulfide with Epoxides via Alkali Metal Alkoxides
关键字：carbonyl sulfide, copolymerization, alkali metal alkoxides, sulfur-containing polymer
Carbonyl sulfide (COS), an analogue of carbon dioxide (CO2), can be converted to CO2 via the carbonic anhydride enzymes widely existing in nature. COS is an ideal monomer for making poly(monothiocarbonate)s, which are difficult to synthesize by traditional methods. Herein, for the first time, we describe an anionic copolymerization of COS with epoxides using alkali metal alkoxides as the catalys...

Controlled Growth of Metal-Organic Frameworks on Polymer Brushes
关键字：grafting density, metal-organic frameworks, polymer brushes, self-initiated photografting and photopolymerization, surface-attached MOF
Polymer brushes are for the first time used to induce the synthesis of metal-organic frameworks (MOFs). The semi-fixed polymer chains provide a confined environment,
which allows a mild growth of MOFs in between polymer chains to give surface-attached spherical MOF nanoparticles, in contrast to the larger MOF cubes/plates formed simultaneously in solution. Polymer brushes bearing carboxylate ...

Ionic-Liquid-Grafted Rigid Poly(p-Phenylene) Microspheres Efficient Heterogeneous Media for Metal Scavenging and Catalysis
关键字：ionic liquids, metal scavenging, microspheres, nanoparticles
Novel guanidinium ionic liquid-grafted rigid poly(p-phenylene) (PPPIL) microspheres have been developed for metal scavenging and catalysis. The noble-metal nanoparticles supported on the microspheres surface can be used as efficient heterogeneous catalysts. The combination of nanoparticles and ionic liquid fragments on the microsphere surfaces enhance the activity and...
