	Abstract:In the present research it is reported the synthesis and characterization of Poly (arylene ether ketone) (PAEK)-cadmium sulfide nanocomposites prepared using carboxylic-functionalized poly (arylene ether ketone) (PCA-PAEK) as the ligand in DMF solutions from Cd(Ac)2 and thiourea. The resulting CdS/PCA-PAEK nanocomposites were characterized by fourier transform infrared spectroscopy, X-ray diffraction, transmission electron microscopy, UV-visible spectroscopy, photoluminescence spectroscopy, confirming the formation of CdS QDs with small particle size with structure. The results of photoluminescence measurement showed that the nanocomposite exhibited distinct luminescence properties. Furthermore, the effects of reaction time, CdS/PCA-PAEK ratio and Cd2+/thiourea ratio on the photoluminescence of CdS QDs were also investigated. Thus, a novel simple route was successfully developed for synthesizing nanohybrids based on quantum dots and high performance polymers with incorporated carboxylic moiety.

	Abstract:In this paper, a series of proton exchange membrane prepared by "Click Reaction" cross-linked water soluble sulfonated poly (ether ether ketone) containing dipropenyl groups (SDPEEK-nE/nH) is reported. Compared with self-crosslinked membranes (SDPEEK-nS), this "Click" cross-linked membranes exhibit extremely reduced water uptake and swelling ratio which used 1,2-Ethanedithiol and 1,6-Hexanedithiol as the cross-linker to apply the "Click"reactions. The lowest proton conductivity of the "Click" cross-linked SDPEEK-7H membrane reaches to 0.168 S cm-1 at 80 oC, and the highest methanol permeability of the "Click" cross-linked SDPEEK-8E is 4.13 × 10-7 cm2 s-1, 5 times lower than that of Nafion117 membrane. All the results imply that the novel thiol cross-linker results the cross-linked membranes are promising alternative material for fuel cell application.

	Abstract:Polyaniline(PANI) doped by natural acid(citric acid, salicylic acid or rosin acid)solutions was synthesized using aniline as monomer and ammonium peroxydisulfate ((NH4)2S2O8) as oxidant. The as synthesized PANI was characterized by using different analytical techniques such as field emission scanning electron microscopy(FE-SEM), Fourier transform Infrared spectroscopy (FT-IR), and X-ray diffraction (XRD). The antibacterial activities of the PANI against Gram positive bacteria(Bacillus megatherium, Bacillus subtilis, Bacillus cereus and Staphylo-coccus aureus) and Gram negative bacteria(Bacillus coli) were investigated. It was shown that PANI doped by different acids exhibited different antibacterial activities against different bacteria. PANI doped by citric acid possesses the better antibacterial activity against the selected species of Gram positive bacteria and Gram negative bacteria than PANI doped by rosin acid. PANI doped by salicylic acid exhibits good antibacterial activities against Gram positive bacteria, but it has little antibacterial activity against the Gram negative bacteria.

	Abstract:Poly(3-methacrylamido phenylboronic acid) (PMAPBA) homopolymer and poly(ethylene glycol)-b-poly(2-acryloxyethyl-galactose) (PEG-b-PAEG) glycopolymer were prepared successfully by reversible addition fragmentation chain transfer polymerization (RAFT) and atom transfer radical polymerization (ATRP), respectively. The formation of boronate crosslinked micelles based on the complexation of PMAPBA and PEG-b-PAEG were confirmed by dynamic light scattering (DLS), thermal analysis, and Alizarin red S (ARS) based colorimetric and fluorescence assay. The micelles showed significant pH, salt, and glucose sensitivity. At pH 5.0 and 6.0, the aggregation and precipitation of the micelles was observed. The particle size increased significantly as pH increased from 7 to 11. Due to shielding of the negatively charged phenylboronic acid groups, the aggregation of the boronate crosslinked micelles were found with increase of the salt concentration. Additionally, the glucose-responsive behavior of the micelles was dependent on the pH value. The sensitivity of the micelles to glucose was stronger at higher pH values.

	Abstract:Three novel soluble alternating conjugated copolymers PT-TZN, PF-TZN, and PBDT-TZN, comprised of thiophene, fluorene, benzo[1,2-b:4,5-b']dithiophene and thiophene derivatives with 3-nitro-1,2,4-triazole side chains, were synthesized via the palladium-catalyzed Suzuki coupling reaction and Stille coupling reaction. The effects of 3-nitro-1,2,4-triazole on the thermal, photophysical, electrochemical and photovoltaic properties were investigated. The introduction of the 3-nitro-1,2,4- triazole side chains benefits to lowering the bandgaps of the polymers. The bulk-heterojunction polymer solar cells were fabricated based on the blend of the as-synthesized polymers and the fullerene acceptor [6, 6]-phenyl-C61-butyric acid methyl ester (PCBM). The maximum power conversion efficiency (PCE = 1.13%) was obtained with PBDT-TZN as the electron donor under the illumination of AM 1.5, 100 mW cm-2. The study results indicate that low bandgap derived from too strong electron-withdrawing groups does not always benefit to the PCEs of PSCs.

	Abstract:Polysaccharides based polyelectrolyte complex nanoparticles (PCNs) intended for use in the delivery of macromolecules were prepared by the self-assembly of deoxycholic acid hydrophobically modified chitosan (CS-DCA) core and then coated with sodium alginate (ALG) shell. The CS-DCA capable of forming nano-sized self-aggregates in medium was prepared by the grafting of DCA to CS. In order to increase the stability of nanoparticles and prevent burst release of drug in bloodstream, polyanionic ALG was coated on the surface of positively charged self-aggregated chitosan nanoparticles to form PCNs. Dynamic light scattering (DLS) results revealed that the mean diameter of the PCNs was about 330 nm, larger than that of uncoated nanoparticles (~150 nm). The zeta potential was big enough to keep the stability of PCNs (28 mV); no size change was found even upon 1 month storage. Bovine serum albumin (BSA) could be easily incorporated into the PCNs with encapsulation efficiency (~ 69%) and keep a sustained manner without burst release when exposed to PBS (pH 7.4). These results suggested that PCNs may be a promising drug carrier for a prolonged and sustained delivery in the bloodstream.

	Abstract:In this paper, [Fe(η-C5H4)2(SiMeCl)]n (PFMCS) has been prepared via the thermal ring-opening polymerization (ROP) of the corresponding strained silicon-bridge [1]ferrocenophanes Fe(η-C5H4)2(SiClMe). The nucleophilic substitution for PFMCS with 2-hydroxyethyl methacrylate (HEMA) afford polymers (HEMA-PFS-a and HEMA-PFS-b) with different pendant methacrylate groups. A remarkable self-assembly of methacrylate-substituted polyferrocenylsilane to form sphere was achieved. Large-compound vesicles (LCVs) were cross-linked by UV. Owing to the number of different pendant methacrylate groups, LCVs behaved as different internal structure and micellar morphologies.

	Abstract:In this paper, the novel PFSs bearing methacrylate and naphthyl functional groups were designed and synthesized in order to further explore the relationship between the structure of polymer and superamolecular organization relation and to obtain stable nanoball. The π-π stacking of naphthalene in the side chain of PFSs probably may afford a novel self-assembly force for self-assembly system of methacrylate and naphthyl-substituted PFS and a stable self-assembly system was obtained after the cross-linking of methacrylate groups.

	Abstract:Density functional theory has been employed to study the homogeneous catalytic copolymerization of styrene with carbon monoxide. The copolymerization reaction is catalyzed by Pd(II) coordinated with 2,2’-bipyridine, a conventional nitrogen-containing bidentate ligand with achiral C2v symmetry. The chain propagation mechanism for the alternating copolymerization as well as the side reactions, including multiple insertions of CO and homopolymerization of styrene, has been investigated. This study focused exclusively on regioisomerism and stereoisomerism. We have demonstrated that the strictly alternating copolymerization is kinetically and thermodynamically favored over the side reactions (i.e., multiple insertions of CO and homopolymerization of styrene). The regiochemistry study indicates the 2,1 type. Furthermore, the stereochemistry study shows that the syndiotactic conformation is preferred over the isotactic or atactic conformations.
