Precise synthesis of sulfur-containing polymers via cooperative dual organocatalysts with high activity
关键字：Metal-free，carbonyl sulfide，100% alternating degree
Metal-free and controlled synthesis of sulfur-containing polymer is still a big challenge in
polymer chemistry. Here, we report a metal-free, living copolymerization of carbonyl sulfide
(COS) with epoxides via the cooperative catalysis of organic Lewis pairs including bases (e.g.:
phosphazene, amidine, and guanidine) and thioureas as hydrogen-bond donors, afford welldefined poly(monothi...

A fluorescein-centered polymer as a phosphor for fabricating pure white light-emitting diodes
关键字：LEDs,fluorescein-centered polymers
White light-emitting diodes (LEDs) are very important energy-saving lighting devices. It is still a big challenge to fabricate pure white LEDs using low-cost, easy-to-process and environment-friendly phosphors. Herein, we report a pure white LED fabricated by combining rationally designed fluorescein-centered polymers with a blue LED chip. Pure white LEDs with Commission International de L’Ecla...

12 In situ chemically crosslinked chitosan membrane by adipic acid
关键字：biodegradable biomaterials biopolymers and renewable polymers
Adipic acid, which is nontoxic, was used to dissolve chitosan. The chitosan/adipic acid solution was used to prepare chitosan membrane. After being heated at 80-100 °C, the membrane was in situ chemically crosslinked by adipic acid, as verified by Fourier transform infrared and wide‐angle X‐ray diffractometer analysis. The crosslinked membrane did not collapse even without treatment in alkaline...

2. Polymerizing Nonfluorescent Monomers without Incorporating any Fluorescent Agent Produces Strong Fluorescent Polymers.
关键字：polymerization induced fluorecent
All the fl uorescent polymers prepared via atom transfer radical polymerization (ATRP) or reversible addition-fragmentation chain transfer (RAFT) are those polymers that have been functionalized with fl uorophore. Prior to our study, it was generally believed that polymerizing nonfl uorescent monomer without incorporating any fluorescent agent only results in polymer without ...
