Two-dimensional (2D) materials have recently attracted significant interest in condensed-matter physics and materials science due to rich intriguing physics and potential applications. Here, by first-principles calculations, we discover a phase of transition-metal dichalcogenides (MoS2 and its family) named the 1H′ phase. We demonstrate that 1H′MoS2 monolayer has multiple topological phase transitions from a topologically trivial insulator state to a 2D type-II Dirac semimetal state, and then to a 2D ideal type-I semimetal state under a moderate tensile strain. The Dirac points are protected by the coexistence of space-inversion (P) and time-reversal (T) symmetry. Our results highlight a family of nonhoneycomb 2D Dirac semimetals with potential application in nanoelectronics.

Preparation and Characterization of Singlehanded Helical Carbonaceous Nanofibers using 1,4-Phenylene Bridged Polybissilsesquioxanes

引用

Journal of Wuhan University of Technology(Materials Science) 2016年第5期31卷 1149-1154页

作者：肖泽丽 GUO Yongmin 李宝宗 LI Yi Jiangsu Key Laboratory of Advanced Functional Polymer Design and Application Department of Polymer Science and Engineering College of Chemistry Chemical Engineering and Materials Science Sooehow University Suzhou 215123 China

Single-handed helical carbonaceous materials attracted much attention for varieties of potential applications. Herein, single-handed helical 1, 4-phenylene bridged polybissilsesquioxane nanofibers were prepared through a supramolecular templating approach using a pair of enantiomers. After carbonization at 700 ℃ for 2.0 h and removal of silica using HF aqueous solution, single-handed helical carbonaceous nanofibers were obtained. The obtained samples were characterized using the field-emission scanning electron microscopy, transmission electron microscopy, N_2 sorptions, X-ray diffraction, Raman spectroscopy and diffuse reflectance circular dichroism（DRCD）. The Raman spectrum indicated that the carbon was amorphous. The DRCD spectra indicated that the carbonaceous nanofibers exhibited optical activity. The surface area of the left-handed helical carbonaceous nanofibers was 907 m^2/g. Such material has potential applications as chirality sensor and supercapacitor electrode.

Conformational Chirality of the Biphenyl Groups Induced by the Aggregation of Poly {bis[4-(4＇-(S)-2-methylbutoxy)- Biphenoxy] Phosphazene}

作者：唐贤慧 LI Baozong 李艺 YANG Yonggang Jiangsu Key Laboratory of Advanced Functional Polymer Design and Application Department of Polymer Science and Engineering College of Chemistry Chemical Engineering and Materials Science Soochow University Suzhou 215123 China

Poly{bis[4-（4＇-（S）-2-methylbutoxy）biphenyloxy]phosphazene}（PP-C） was designed and successfully synthesized, and then characterized by means of FT-IR spectroscopy, ~1H- and ^（31）P-NMR, GPC spectroscopy, wide angle X-ray diffraction and differential scanning calorimetry. The results indicated that for PP-C, the M_w is 2.18×10~5 and the PDI is 1.96. PP-C was a kind of crystallized polymer with a crystallizing point of -2.0 ℃ and a melting point of 28 ℃. The conformational chirality of the PP-C molecules was studied using circular dichroism spectrum. It was found that in dilute THF solution, the biphenyl groups in the PP-C molecules twisted randomly. However, when the PP-C formed aggregates, the biphenyl groups tended to twist single-handedly, which was controlled by the adjacent chiral alkoxy groups.

We are currently exploring all-aromatic copoly（ester-imide）s based on N-（3'-hydroxyphenyl）trimellitimide（IM） and 4-hydroxybenzoic acid（HBA）.Two different crystal phase polymers with molar ratio of IM/HBA as 0.3/0.7（semi-crystalline） and 0.7/0.3（amorphous） were obtained from a one-step melt polymerization method, namely 3-IM/7-HBA and 7-IM/3-HBA, *** both cases, thermoplastic polymers were obtained with a high volume fraction of infusible crystalline poly（HBA） or amorphous poly（IM）.Composite films prepared by melt pressing are brittle but upon stretching（stretch ratios of 4 are possible） above their glass transition temperature（T） their ductility improves *** to different reinforcement mechanisms, the two molecular composites exhibit different thermo-mechanical properties.3-IM/7-HBA composite films show a strong dependence of the T on the stretch *** as prepared films exhibit a T of 205 ℃ and the T increased to 248 ℃ after stretching the films 3 times above *** tensile strength and elongation at break of the film increased by 0%（78 MPa） and 5%（3% elongation）, respectively after one stretching *** the case of 7-IM/3-HBA, an increasing trend was observed in storage modulus（E'）.The room temperature storage modulus increased from 7 to 28 GPa after 3 stretching *** this case, however, there is no effect on *** as-prepared films could not be handled（too brittle） but after stretching the film once above T, a tensile strength of 161 MPa and elongation of 9% was *** the best of our knowledge, such improvements in thermo-mechanical properties in all-aromatic main-chain polymers have not been reported before.

Synthesis and properties of three novel rhodamine-based fluorescent sensors for Hg^(2+)

Chinese Chemical Letters 2016年第6期27卷 989-992页

Three novel rhodamine-based Hg^2＋ fluorescent sensors were designed and synthesized. The sensors could work in semi-aqueous solutions with nearly neutral p H and showed high selectivity and sensitivity to Hg^2＋ with remarkable fluorescence enhancement. For these three sensors, the linear working range broadened（0–80, 0–100 and 0–140 μmol/L, respectively） and the sensitivity increased（7.7, 15.5 and 17.6 folds of the fluorescence enhancement and 512, 66.2 and 37.6 ppb of the detection limit） with the rising of the thiourea-unit numbers. Furthermore the sensors exhibited excellent interference immunity to multiple environmentally and biologically relevant metal ions. Pond and tap water assay showed good practicability of the sensors. The number of the bound Hg^（2＋） equaling to that of the thiourea units and the irreversible recognition process implied a new interaction way between Hg^（2＋） and the sensor.
