Synthesis of indole-based functional polymers with well-defined structures via a catalyst-free C–N coupling reaction
关键字：Poly(N-arylene diindolylmethane)s, C–N coupling reaction
Poly(N-arylene diindolylmethane)s (PMDINs) with precise structures and high molecular weights (Mw up to 389 200) in high yields (up to 95%) were synthesized by the catalyst-free nucleophilic substitution polycondensation of 3,30-diindolylmethane with different activated difluoro monomers via a C–N coupling reaction process. A model reaction was carried out to assist in determining the optimal r...

Flame Retardant Electrical Conductive Nano-polymers based on Bisphenol F Epoxy Resin Reinforced with Nano Polyanilines
关键字：Flame Retardant, Epoxy Resin, Nano Polyanilines
Both fibril and spherical polyaniline (PANI) nanostructures have successfully served as nanofillers for obtaining epoxy resin polymer nanocomposites (PNCs). The effects of nanofiller morphology and loading level on the mechanical properties, rheological behaviors, thermal stability, flame retardancy, electrical conductivity, and dielectric properties were ...

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.

Progress on High Performance Polymers Bearing Phthalazinone Moieties and Their Applicaion Technologies
关键字：high performance polymer, poly(aryl ether)s, phthalazinone, thermoplastic composites
Rising oil price and pressure to reduce emission push aerospace Original Equipment Manufacturers (OEMs) to use more and more polymer matrix composites (PMC) to reduce weight.Secondly, OEMs also try their best to reduce cost. They keep their eyes on improving repair and maintenance of PMC. Thermoplastics possess excellent comprehensive performance. First of all,OEMs prefer their high toughness,...

One-Step Synthesis of a Thienylenepyridazinylenethienylene-based Coil-Rod-Coil Copolymer with Enhanced Emission and Improved Fluorescence Stability
关键字：aggregation，block copolymers，conjugated polymers，fluorescence，oligomers
A new coil-rod-coil copolymer is synthesized via Sonogashira coupling using one-step methodology. The copolymer PEG-OEPETPT-PEG constitutes of poly(ethylene glycol) (PEG) as the coil block, and oligo[p-(ethynylenephenyleneethynylene)-alt-(thienylenepyridazinylenethienylene)] (OEPETPT) as the rod segment. The conjugated polymer PEPETPT with the same conjugated building blocks is also synthesized fo...

Preparation of Fluorescent Conjugated Polymer Films with Different Emission Colors: Investigation into the Influences of Chemical Structure and Morphology
关键字：chemical structures，conjugated polymers，films，fluorescence，morphology
A series of PPV fi lms with different fl uorescent emission colors are prepared using a facile approach. Modifi ed from the conventional Wessling route, the labile sulfonium groups in the polymer precursor (pre-PPV) are partly substituted to various degrees by relatively stable methoxy groups, followed by a regular thermal elimination step to obtain PPV. Different chemical structures among these...
