    摘要:
    在过去的四十多年中,沸石基催化剂的设计依赖于富铝框架与碱金属阳离子(优选Cs+)的交换。然而,受限于接入和扩散的中等活性,以及高铯含量(通常超过30%)所带来的高制造成本,迄今为止,这些催化剂的工业应用一直受到阻碍。在此,我们发现高硅USY沸石在精细化工行业相关的多种碱催化反应及生物燃料升级中,优于铝富集的同类催化剂。通过后合成改性引入晶内介孔网络,缓解扩散限制,这类材料的优势得以增强。例如,所得到的无阳离子层级USY在Knoevenagel缩合反应中的活性比基准的Cs–X高出多达30倍,而在液相(硝基)醛缩合反应中也获得了类似的结果。此外,在丙醛的气相醛缩合反应中,高硅沸石相比含铯沸石甚至强固体碱(如MgO)提供了更优越的活性、选择性和使用寿命。我们将介孔性和内在沸石特性(如晶体结构)之间复杂的相互作用进行解耦,并量化了依赖于反应物大小的层级结构对催化剂有效性的提升。获得的结果为解决沸石催化的缺陷迈出了重要一步,从而重新激发了其在工业应用中的潜力。

    Seven aromatic hydrocarbons bearing a dicyanovinyl unit were prepared to determine the relationship between both the number of aromatic rings and location of acceptor substituent on their thermal and optoelectronic properties. Additionally, the density functional theory calculations were performed. The obtained compounds showed temperatures of the beginning of thermal decomposition in the range of

    Synthetic supercontainers constructed from divalent metal ions, carboxylate linkers, and sulfonylcalix[4]arene‐based container precursors exhibit great promise as enzyme mimics that function in organic solvents. The capacity of these artificial hosts to catalyze Knoevenagel condensation can be switched on when the aldehyde substrate possesses a molecular size and shape matching the nanocavity of the

    A highly water stable zinc metal–organic framework (ZnMOF), [Zn(HL)2]}n, was synthesized using a triazole–carboxylate-based mixed ligand (L = 5-(4H-1,2,4-triazol-4-yl)isophthalic acid). A 2D MOF was formed by hydrothermal synthesis, and extended to a 3D supramolecular network through strong hydrogen bonding.

  • Intramolecular charge transfer properties of dicyanovinyl-substituted aromatics
    作者:Alan R. Katritzky、Dong Wei Zhu、Kirk S. Schanze
    DOI:10.1021/j100168a007
    日期:1991.7
    A series of five dicyanovinyl (DCV)-substituted aromatic compounds (referred to collectively as Ar-DCV, where Ar = 1-phenyl, 1-napthyl, 9-anthracenyl, 9-phenanthrenyl, and 1-pyrenyl) were prepared and their ground- and excited-state properties were examined. Solvent-dependent NMR studies indicate that the ground state of the Ar-DCV compounds is polar. Strong intramolecular charge transfer (ICT) absorption bands were observed for each compound. The position of the ICT absorption is nearly independent of solvent polarity and the molar absorptivity is related to the twist angle between the aromatic donor and the DCV acceptor. The fluorescence spectra are highly solvatochromatic and the fluorescence energy correlates with the solvent polarity parameter-DELTA-f in a variety of solvents. The fluorescence quantum yields are low and no emission was observed from phenyl-DCV. An excited-state model is proposed which explains the solvent dependence of the ICT absorption and emission of the series of Ar-DCV compounds.
