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...

Side-On Main-Chain Liquid Crystalline Polymers Prepared by Acyclic Diene Metathesis Polymerization and Thiol-Ene Click Step-Growth Polymerization
关键字：LCP
In this manuscript, we design and synthesize a
series of X-shaped mesogenic monomers, bearing two terminal-alkene tails.
Starting from these X-shaped monomers, acyclic
diene metathesis polymerization and thiol-ene polyaddition are applied for the first time to prepare two series
of side-on main-chain liquid crystalline polymers respectively.
