论文题目:Aromatic Extension at 2,6-Positions of Anthracene toward an Elegant Strategy for Organic Semiconductors with Efficient Charge Transport and Strong Solid State Emission

论文作者:Jie Li, Ke Zhou, Jie Liu, Yonggang Zhen, Li Liu, Jidong Zhang, Huanli Dong, Xiaotao Zhang, Lang Jiang, Wenping Hu

论文摘要:Organic semiconductors integrating excellent charge transport with efficient solid emission are very challenging to be attained in the construction of light-emitting transistors and even for realization of electrically pumped organic lasers. Herein, we introduce naphthyl units at 2,6-positions of anthracene to achieve 2,6-di(2-naphthyl)anthracene (dNaAnt), which adopts J-aggregated mode in the solid state as a balanced strategy for excellent charge transporting and efficient solid state emission. Single crystal field-effect transistors show mobility up to 12.3 cm2·V–1·s–1 and a photoluminescence quantum yield of 29.2% was obtained for dNaAnt crystals. Furthermore, organic light-emitting transistors (OLETs) based on dNaAnt single crystals distribute outstanding balanced ambipolar charge transporting property (μh = 1.10 cm2·V–1·s–1, μe = 0.87 cm2·V–1·s–1) and spatially controllable emission, which is one of the best performances for OLETs.

论文题目:A photovoltaic self-powered gas sensor based on a single-walled carbon nanotube/Si heterojunction

论文作者:L. Liu, G. H. Li, Y. Wang, Y. Y. Wang, T. Li, T. Zhang, S. J. Qin

发表日期:10 August 2017

论文摘要:We present a novel photovoltaic self-powered gas sensor based on a p-type single-walled carbon nanotube (SWNT) and n-type silicon (n-Si) heterojunction. The energy from visible light suffices to drive the device owing to a built-in electric field (BEF) induced by the differences between the Fermi levels of SWNTs and n-Si.

论文题目:Bioorganometallic ferrocene-tripeptide nanoemulsions

论文作者:Xuejiao Yang, Yuefei Wang, Wei Qi, Rongxin Suabc, Zhimin Hea

发表日期:20 July 2017

论文摘要:We demonstrate an effective strategy to prepare highly stable nanoemulsions using ferrocene-modified tripeptides. Compared with traditional nanoemulsions, bioorganometallic peptide nanoemulsions are appealing for a number of reasons, including long-term and outstanding thermal stability, redox activity and biocompatibility. The formed nanoemulsions could remain stable for more than four months at room temperature, which is the highest stability reported so far for peptide and protein emulsifiers. The phase behaviour and size distribution of the emulsions could be precisely tailored by altering the temperature, solvent ratio and redox state of the ferrocene moiety. In this process, we observed a unique enthalpy-driven phase transition from nanoemulsions to hydrogels, which could be attributed to the competition between the interfacial free energy and the association energy among the self-assembling peptides. Moreover, we could impart catalytic activity to the nanoemulsions through rationally altering the sequence of the tripeptides. The structurally tunable, functional bioorganometallic nanoemulsions offer new opportunities in many areas including drug delivery, and the food and cosmetic industries.

论文题目:A C-HCR assembly of branched DNA nanostructures for amplified uracil-DNA glycosylase assays

论文作者:Jing Wang, Min Pan, Jie Wei, Xiaoqing Liua, Fuan Wang

发表日期:10 October 2017

论文摘要:An autonomous nonenzymatic DNA machine has been successfully engineered based on a two-layered cascaded hybridization chain reaction (C-HCR) circuit, in which the tandem outputs of the upstream HCR-1 unit activate the downstream HCR-2 unit to induce successive repeated hybridizations, generating branched DNA structures and enabling sensitive and selective detection of uracil-DNA glycosylase and its inhibitors.

论文题目:Identification of activity trends for CO oxidation on supported transition-metal single-atom catalysts

论文作者:Haoxiang Xu, Cong-Qiao Xu, Daojian Cheng, Jun Li

发表日期:06 October 2017

论文摘要:Single-atom catalysts (SACs) can have high selectivity while maximizing the efficient utilization of metal atoms and are very promising for applications in catalysis. However, the design and development of SACs cannot be effectively achieved, as little theoretical effort has been directed towards exploring the activity trends for reactions on SACs. In this work, we find that there is a Brønsted–Evans–Polanyi (BEP) linear correlation between the adsorption energies of CO and O2 and transition state energies for CO oxidation on various M/MgO and M/Fs-defect MgO SACs (M = Cu, Ag, Au, Ni, Pd, and Pt) via density functional theory (DFT) calculations. Based on the contour plot of Sabatier activity from the BEP relationships and microkinetic model, we have identified the activity trends for CO oxidation on these SACs by using the adsorption energies of CO and O2 as the activity descriptors. The theoretical calculations indicate that Ag/MgO and Ag/Fs-defect MgO exhibit better catalytic performance than the other SACs. Our results provide a general picture of the identification of the activity trends for CO oxidation on MgO-supported SACs in terms of the adsorption energies of the reactants. This approach may also lay a theoretical basis for designing new SACs for reactions other than CO oxidation.

论文题目:Microwave-assisted synthesis of glycopolymers by ring-opening metathesis polymerization (ROMP) in an emulsion system

论文作者:Fei Fan, Chao Cai, Lei Gao, Jun Li, Ping Zhang, Guoyun Li,  Chunxia Li, Guangli Yu

发表日期: 12 September 2017

论文摘要:The protecting-group-free synthesis of versatile glycopolymers accelerated by microwave irradiation in an emulsion system is presented herein. Copper-catalyzed azide–alkyne cycloaddition (CuAAC) was employed to prepare a wide range of glycosylated hydrophilic monomers, and a series of glycopolymers were fabricated via ring-opening metathesis polymerization (ROMP). Our data revealed that phase transfer catalysis (PTC) in an emulsion system was more superior to that of homogeneous solvents (organic and aqueous solvents). Grubbs 2nd, Grubbs 3rd, and Hoveyda–Grubbs 2nd (H–G 2nd) catalysts were systematically screened from room temperature to 75 °C, of which the H–G 2nd catalyst exhibited more compatibility with microwave irradiation in emulsion polymerization. The efficiency of polymerization was significantly enhanced under microwave irradiation that was completed in less than 5 min for homopolymerization and within 15 min for multi-block polymerization. Six glycopolymers were successfully synthesized under optimum conditions. In addition, the surface plasmon resonance (SPR) analysis indicated that the mannose-functionalized multi-block glycopolymers (p-Glu-b-Man and p-Glu-b-Man-b-Fuc) exhibited dramatic improvements in their binding affinities to concanavalin A (ConA) as compared to the homoglycopolymer (p-Man). The robust approach developed in this study offers the efficient fabrication of versatile glycopolymers for potential biological and medical applications.

论文题目:A review of nanocarbons in energy electrocatalysis: Multifunctional substrates and highly active sites

论文作者:ChengTang, Maria-MagdalenaTitirici, QiangZhang

发表日期:November 2017

论文摘要:Nanocarbons are of progressively increasing importance in energy electrocatalysis, including oxygen reduction, oxygen evolution, hydrogen evolution, CO2 reduction, etc. Precious-metal-free or metal-free nanocarbon-based electrocatalysts have been revealed to potentially have effective activity and remarkable durability, which is promising to replace precious metals in some important energy technologies, such as fuel cells, metal–air batteries, and water splitting. In this review, rather than overviewing recent progress completely, we aim to give an in-depth digestion of present achievements, focusing on the different roles of nanocarbons and material design principles. The multifunctionalities of nanocarbon substrates (accelerating the electron and mass transport, regulating the incorporation of active components, manipulating electron structures, generating confinement effects, assembly into 3D free-standing electrodes) and the intrinsic activity of nanocarbon catalysts (multi-heteroatom doping, hierarchical structure, topological defects) are discussed systematically, with perspectives on the further research in this rising research field. This review is inspiring for more insights and methodical research in mechanism understanding, material design, and device optimization, leading to a targeted and high-efficiency development of energy electrocatalysis.
