Finely controlled circularly polarized luminescence (CPL) supramolecular polymerization based on a tetraphenylethene core with four l- or d-alanine branch side chains (l-1 and d-1) in the solution state is presented, resulting from the tuning of mechanical stimulus. Weak, green emissions of l-1 and d-1 in tetrahydrofuran (THF) were converted into strong blue emissions by tuning the mechanical stimulus. The strong blue emissions were caused by an aggregation-induced emission (AIE) effect during the formation of a supramolecular polymer. Lag time in the supramolecular polymerization was drastically reduced by the mechanical stimulus, which was indicative of the acceleration of the supramolecular polymerization. A significant enhancement of circular dichroism (CD) and CPL signals of l-1 and d-1 was observed by tuning the rotational speed of the mechanical stimulus, implying that the chiral supramolecular polymerization was accelerated by the mechanical stimulus.

Due to the environmental and energy issues in the world, the chemical fixation of carbon dioxide into valuable products has been attracted many attentions in the recent years. However, the utilization of the highly chemical stabile carbon dioxide requires high bond cleavage energy of C=O bond. Thus, seeking and developments of the suitable catalysts for the chemical fixation of carbon dioxide is quite important. Metal-organic frameworks (MOFs), as a kind of porous materials, exhibit intriguing structural diversity and outstanding physical and chemical properties. Their modular nature and facile tunability make these materials ideal heterogeneous catalysts because they possess active sites and accessible channels for the attraction and retention of substrates. In this review, we intended to discuss the recent advances on some of the most interesting chemical fixation catalysis starting fromCO2 based on MOFs materials as heterogeneous catalysts under different conditions. Among all these excellent works, we hope to find and highlight the effective approaches and technique in this field, and analyze the opportunities and limitations for the MOFs catalysts for the future applications.

Catalysis of C1 chemistry, especially for carbon monoxide (CO), carbon dioxide (CO2) and methane (CH4), is critically important for the clean production of fuels and chemicals and future energy sustainability. However, due to the relatively inert nature and low reactivity of these C1 molecules, their activation and transformation into clean fuels and high value-added chemicals still remain formidable challenges. In this context, metal-organic frameworks (MOFs), as relatively new emerging crystalline porous materials, have been shown to be promising heterogeneous catalysts or supports/precursors in the design and synthesis of various functional nanomaterials for addressing these challenges. In this review, the recent advances in MOF-based heterogeneous catalysts for transforming CO, CO2 and CH4 into high value-added chemicals are systematically reviewed. Emphasis is mainly placed on the catalytic reactivity, reaction mechanism and catalyst design. Additionally, major challenges and opportunities for MOF catalysts in the conversion of C1 chemistry are discussed to outline aspects for further development in this ongoing research field. It is anticipated that this review will provide a useful guide to chemists and material scientists attempting to design better MOF-based catalysts for the chemical conversion of C1 compounds.

Due to serious environmental pollutions, the detection of hazardous and explosive nitro-aromatic compounds using metal-organic frameworks (MOFs) have been a promising research field in the current scenario. Here, we report a new fluorescent MOF, [Zn2(TCPE)(tta)2]·2DMF·4H2O·2Me2NH2 + (HNU-34, H4TCPE = 1,1,2,2-tetra(4-carboxylphenyl)ethylene, 1H-tta = 1H-tetrazole) which possesses a 3D configuration and 1D channels along the c-axis. It can serve as a luminescence sensor for the detection of nitrophenol explosives through different quenching effects, especially for the mononitrophenol and dinitrophenol. The detection limits of 2,6-dinitrophenol and trinitrophenol are 29.45 nM and 36.15 nM, respectively, which are among the high level of the reported MOF sensors, especially for DNP.

An Aggregation Induced Emission (AIE) transduction mechanism has been used to detect nitric oxide (NO). A new tetraphenylethylene derivative functionalized with alkyne moieties has been prepared to work as a fluorescent probe. A ?click? reaction was chosen because NO is able to generate the required catalytic species by reducing Cu(II) to Cu(I).

Sensing and capture of toxic and hazardous gases and vapors by metal-organic frameworks

Toxic and hazardous chemical species are ubiquitous, predominantly emitted by anthropogenic activities, and pose serious risks to human health and the environment. Thus, the sensing and subsequent capture of these chemicals, especially in the gas or vapor phase, are of extreme importance. To this end, metal-organic frameworks have attracted significant interest, as their high porosity and wide tunability make them ideal for both applications. These tailorable framework materials are particularly promising for the specific sensing and capture of targeted chemicals, as they can be designed to fit a diverse range of required conditions. This review will discuss the advantages of metal-organic frameworks in the sensing and capture of harmful gases and vapors, as well as principles and strategies guiding the design of these materials. Recent progress in the luminescent detection of aromatic and aliphatic volatile organic compounds, toxic gases, and chemical warfare agents will be summarized, and the adsorptive removal of fluorocarbons/chlorofluorocarbons, volatile radioactive species, toxic industrial gases and chemical warfare agents will be discussed.
