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...

Polydiacetylene-Polymethylmethacrylate/Graphene Composites as One-Shot, Visually Observable, and Semiquantative Electrical Current Sensing Materials
关键字：polydiacetylene, graphene, electrochromic material, sensing, semiquantative
Aiming to develop pH-paper-like current sensing materials, we prepared irreversible electrochromic PDA-PMMA/graphene composites. The composites exhibited an excellent linear relationship between critical responsive currents and the amount of graphene in the system. In these composites, PDA acted as the electrochromic material and graphene as the conductive matrix. The presence of PMMA not only ens...

A Challenge to Stable Extrusion Foaming of Ternary Blends of One Branched and Two Linear PP and Evaluation of Rheological Parameters
关键字：Polypropylene foam; Melt elasticity; Cell population density.
Polypropylene is a linear crystalline material, which shows low melts extensibility. The processing window in extrusion foaming of linear PP is narrow[1], and the setting parameters are necessary to be optimized together with improving...

One-pot synthesis of amphiphilic Janus gold nanoparticles with Dpenicillamine and benzyl mercaptan ligands by toluene/water emulsion reaction
关键字：Amphiphilic, Janus, Gold nanoparticle, Emulsion reaction
Amphiphilic Janus Au NPs were synthesized by emulsion reaction with presence of D-penicillamine (D-PA) and benzyl mercaptan (BM) molecules at water and toluene phases, respectively. TEM and XRD characterizations indicate that the reaction product is composed of Au nanocrystals in size of 2.9 nm. XPS, FTIR, Raman and 1H NMR analyses suggest that the capping ligands on the Au NPs are D-PA and BM, ...
