Traditional silicone materials have poor mechanical properties,poor interfacial adhesion and lack the ability to be reprocessed or recycled.Herein,we developed a novel strategy of incorporating dynamic noncovalent bonds(2-amino-4-hydroxy-6-methylpyrimidine(UPy))into side chain of silicone backbones to construct supramolecular silicone poly(urea-urethane)(SSPu)coatings with excellent mechanical performance,strong interfacial adhesion and multiple time recycling capability.Impressively,the prepared SSPu is endowed with simultaneously enhanced stiffness(272.0±23.2 MPa)and toughness(8.0±2.0 MJ·m^(-3)).Besides,SSPu shows strong interfacial adhesion(up to 9.0±1.3 MPa)to diverse substrate(stainless steel,aluminum,copper,epoxy and glass)with long term stability.Moreover,SSPu exhibits excellent multirecyclability and reusability without significantly decrease of its performance.In addition to the abovementioned features,the enrichment of siloxane backbones in the surface layer endows SSPu with robust repellency to water/oil.Our strategy provides a powerful route to fabricate a new multifunctional silicone elastomer.It is highly anticipated that our strategy can effectively extend the service life of silicone coating which can be applied in a wide variety of areas including self-cleaning,antifouling.

Hyper-crosslinked polymers （HCPs） are promising materials for gas capture and storage because of their low cost and easy preparation. In this work, we report the massive preparation of coumarone-indene resin-based hyper-crosslinked polymers via one-step Friedel-Crafts alkylation. Low-cost coumarone-indene resin serves as the new building block and chloroform is employed as both solvent and external crosslinker. A maximum surface area of 966 m2·g-1 is achieved, which is comparable with that of previously-reported coal tar-based porous organic polymers. Most importantly, a large number of heteroatoms including inherent oxygen atoms and introduced chlorine atoms in obtianed HCPs further enhance the interaction between specific sorbate molecule and adsorbent. Therefore, optimal structural and chemical property endow the new coumarone-indene resin-based HCPs with decent gas storage capacity （14.60 wt% at 273 K and 0.1 MPa for CO2; 1.18 wt% at 77.3 K and 0.1 MPa for H2）. These results demonstrate that new HCPs are potential candidates for applications in CO2 and H2 capture.

Although the construction of specific functional crystalline materials is still challenging,the multi-component molecular assembly has become a key solution for the design of functional materials.Here,we report a hydrogen-bonded organic framework(HOF)material FJU-360 constructed from disodium 6‑hydroxy-5-[(4-sulfophenyl)azo]-2-naphthalenesulfonate(SSY)and terephthalimidamide.The charge-assisted hydrogen bonding between amidinium and sulfonate makes FJU-360 produce much stronger fluorescence than SSY,and can be used as a luminescence sensor to rapidly quench aniline through luminescence quenching.FJU-360 is sensitive and highly selective for the detection of aniline,and the detection limit reached 3.2 nmol/L,which is the lowest value reported currently.The mechanism of aniline response was analyzed through the aniline@FJU-360 single crystal structure,and the luminescence mechanism was clarified through density function theory calculations.This work is an important step towards the rational synthesis and assembly of sensing materials.

金属有机框架(MOF)和应力发光(ML)材料被认为是两种有前途的材料,并在诸多领域得到了广泛应用.若能将二者结合起来获得ML-MOF材料,则势必会拓展它们的应用范围.但目前对MLMOF的研究并不多,且其中的ML机制仍不明确.在本研究中,我们提出了一种通过在非中心对称SBD MOF中掺杂镧系离子来开发ML-MOF的策略,成功合成了一系列具有多色应力发光的镧系掺杂MOF Ln-SBD(Ln=Tb,Dy,Sm,Eu)和Tb1-xEux-SBD(x=0.2,0.4,0.6,0.8).镧系离子均匀分布在SBD基质中,并部分占据了Sr的格位.通过改变共掺比例和掺杂种类,ML-MOF表现出了从绿色到黄色再到红色的多色应力发光.相似的ML和PL光谱表明,ML发射与镧系离子从激发态到基态的辐射跃迁有关.辐射跃迁是由电子轰击过程引起的,而电子轰击过程源于非中心对称SBD基质的压电效应.本文首次开展了基于ML的温度传感研究,这有望在没有激发光源的情况下实现应力和温度的双重功能检测.结合MOF的多功能性和ML发射,本研究为开发更多用途、更有趣的多功能材料提供了独特的见解,同时拓展了MOF和ML材料的应用范围.

The morphology evolution of the mesoporous magnetic composite nanospheres Fe3O4@Poly（4- vinylpyridine） during the formation process and its absorption property of Congo red were studied in this study. A simple solvothermal method was applied for the fabrication of Fe3O4@Poly（4-vinylpyridine） composites with regular structure and uniform size distribution in the presence of 4-vinylpyridine as the structure inducer. The morphology, structure and magnetism performance were characterized and the adsorption model and mechanism were discussed. The results showed that the Fe3O4@Poly（4- vinylpyridine） composites were efficient adsorbent for the removal of Congo red from water and it could be reused by a magnetic separation. The adsorption isotherm of Congo red on Fe3O4@Poly（4- vinylpyridine） composites was fitted well with the Langmuir adsorption model.

The phase equilibria in the Co-Ti-Re ternary system at 800,1000,1100 and 12000C were studied combined with electron probe microanalyzer(EPMA),X-ray diffraction(XRD),scanning electron microscope(SEM)and transmission electron microscope(TEM).The new phaseτwith a large solubility was discovered at all four isothermal sections,and its structure still needs a further study.A large solubility of Re in the CoTi phase was observed.The solubility of Re in the Co_(3)Ti phase is6.1%at 800℃,8.7%at 1000℃and 7.7%at 1100℃.The present work could be significant for alloy design of Co-based alloys and thermodynamic analysis of the Co-TiRe ternary system.

The morphological evolution and precipitation kinetics of γ′ and D0(CoW) phase in Co–Al–W alloys at 900 °C have been studied by applying Phase-field method and experiment in order to understand the transformation process of γ′ phase and D0phase. The growth processes of D0phase and precipitation of γ′ phase under elastic fields were simulated through coupling with thermodynamics and dynamics databases. The simulation results indicate that the misfit δ≥ 0.53% has a greater impact on γ′ particle morphology in γ/γ′ structure.Co–Al–W alloy with low Al and high W is one of the factors to promote the precipitation of D0phase. Three stages during aging, namely the γ′ phase incubation stage, the γ′ phase fast nucleation and growth stage, and the transformation from γ′ phase to D0phase stage can be observed with the non-constant coarsening rate that varying with the decrease of γ′ phase. The particle size distribution(PSD) during the precipitation of D0phase is more in line with MLSW theory than LSW theory. This simulation results are in good agreement with the experiment results to help analyze microstructure evolution of Co–Al–W alloy.

All-solid-state thin-film lithium batteries(TFLBs)are the ideal wireless power sources for on-chip micro/nanodevices due to the significant advantages of safety,portability,and integration.As the bottleneck for increasing the energy density of TFLBs,the key components of cathode,electrolyte,and anode are still underway to be improved.In this review,a brief history of TFLBs is first outlined by presenting several TFLB configurations.Based on the state-of-the-art materials developed for lithium-ion batteries(LIBs),the challenges and related strategies for the application of those potential electrode and electrolyte materials in TFLBs are discussed.Given the advanced manufacture and characterization techniques,the recent advances of TFLBs are reviewed for pursuing the high-energy-density and long-termdurability demands,which could guide the development of future TFLBs and analogous all-solid-state lithium batteries.

Inverse vulcanized polymers(IVPs) that generated from elemental sulfur and smaller amounts of alkenes have found broad promising applications such as cathode materials for Li-S batteries, dynamic and repairable materials, optics applications, and metal sorption. However, their exploration in organic synthesis is still unprecedented. Here we first report the application of inverse vulcanized polymers in catalysis for organic transformations. A biomass-derived inverse vulcanized polymer(IVP-EAE) is found to be capable of catalyzing cross-coupling reactions in a transition-metal-free fashion under visible light.This method allows the direct C–H functionalization of pyrroles and N-arylacrylamides with(hetero)aryl halides, respectively, leading to the formation of two sets of structurally important scaffolds including pyrrole-containing biaryls and 3,3-disubstituted oxindoles with high selectivity. We anticipate this study will not only unveil the new potential of IVPs, but also offer a distinct type of catalysts for organic transformations.
