Supramolecular Host Guest(超分子主客)研究综述
Supramolecular Host Guest 超分子主客 - The addition of beta-cyclodextrin (β-CD) to the extraction phase led to enhance extraction efficiencies, probably through the selective supramolecular host-guest inclusion of TCs. [1] The β-CD@PEI-Fc chiral interface was prepared based on the supramolecular host-guest interaction between ferrocene (Fc) grafted polyethyleneimine (PEI-Fc) and chiral β-cyclodextrin (β-CD). [2] The supramolecular host-guest interactions of this P(DMAEMA-co-NaphtA) copolymer with the electron-deficient CBPQT4+, 4 Cl- cyclophane host were studied by 1H NMR spectroscopy, UV-Visible spectroscopy and isothermal titration calorimetry (ITC), revealing, a high association constant of 6. [3] Supramolecular host-guest systems are generally at thermodynamic equilibrium state or in a kinetically trapped state. [4] Anthracene (AN) forms two types of supramolecular host-guest complexes (2:1 and 2:2, H:G) with the synthetic host octa acid in aqueous medium. [5] We rationally designed and developed a novel Eu3+/Tb3+ supramolecular assembly hybrids (Eu/Tb-SAH) by supramolecular host-guest recognition and coordination recognition with the excellent characteristics of water dispersion stability, biocompatibility and luminous properties. [6] In the present study, we develop a coenzyme-mediated supramolecular host-guest semibiological system that combines artificial and enzymatic catalysis for photocatalytic hydrogen evolution from alcohol dehydrogenation. [7] Herein, a smart plant hormone delivery system based on metal-organic frameworks (MOFs) and supramolecular nanovalves, namely gibberellin (GA)-loaded CLT6@PCN-Q, is constructed through supramolecular host-guest interaction to regulate the growth of dicotyledonous Chinese cabbage and monocotyledonous wheat. [8] It highlights 2D chirality induction phenomena through a classic "sergeants-and-soldiers" mechanism, in which the inducer is incorporated into a network component, as well as through a "supramolecular host-guest" mechanism, in which the inducer is entrapped in the porous space, leading to counterintuitive chirality reversal. [9] The breathing phenomenon in metal-organic frameworks (MOFs) has revealed supramolecular host-guest interactions, which could be beneficial for chemical separation in numerous industrial applications. [10] The study thus demonstrates the suitability of VCD spectroscopy for the characterization of analogous supramolecular host-guest complexes. [11] To this end, the optimized supramolecular host-guest (p-sulfonatocalix[4]arene-oxazine 1) reporter pair and FMO3 catalytic system were exploited to determine the influence of the bioactive compounds in XFZYD on the conversion from TMA to TMAO. [12] Owing to the supramolecular host-guest interactions of pillar[5]arene/neutral nitrile molecular recognition motif, the designed molecules could be spontaneously self-assembled. [13] By the combination of various external stimuli, these fluorescent supramolecular host-guest systems could reveal interesting photoluminescence (PL) properties in DMF/H2O (1:1, v/v) solutions, including bifluorophoric host-guest systems after the complexation of Al3+ ion, i. [14] The accurate determination of ultra-high binding affinities in supramolecular host-guest chemistry is a challenging endeavour because direct binding titrations are generally limited to affinities <106 M-1 due to sensitivity constraints of common titration methods. [15] Binding affinity and intermolecular interactions are essential characteristics that could be used to comprehend molecular recognition between molecules in supramolecular host-guest systems. [16] To this endeavor, herein we successfully fabricated a novel biogenic amine-responsive platform (P-N) based on supramolecular host-guest interaction, exploiting self-assembly properties of phenazine derivatives (PY) and naphthalene diamide (NDI) induced by hydrogen bond. [17] The combination of thermoresponsive polymers with supramolecular host-guest interactions enables accurate tuning of the phase transition temperature, while also providing additional response mechanisms based on host-guest complexation. [18] These ways all further increase the diversity of photo- chemical and/or physical properties of supramolecular host-guest systems. [19]在萃取相中添加 β-环糊精 (β-CD) 可提高萃取效率,这可能是通过选择性超分子主客体包含 TC。 [1] 基于二茂铁(Fc)接枝聚乙烯亚胺(PEI-Fc)和手性β-环糊精(β-CD)之间的超分子主客体相互作用制备β-CD@PEI-Fc手性界面。 [2] 通过 1H NMR 光谱、紫外-可见光谱和等温滴定量热法 (ITC) 研究了这种 P(DMAEMA-co-NaphtA) 共聚物与缺电子 CBPQT4+, 4 Cl- 环芳主体的超分子主客体相互作用,揭示,高关联常数为 6。 [3] 超分子主客体系统通常处于热力学平衡状态或动力学捕获状态。 [4] 蒽 (AN) 在水性介质中与合成的主体八酸形成两种类型的超分子主客体复合物(2:1 和 2:2,H:G)。 [5] 我们通过超分子主客体识别和配位识别,合理设计开发了一种新型的Eu3+/Tb3+超分子组装杂化物(Eu/Tb-SAH),具有水分散稳定性、生物相容性和发光特性等优良特性。 [6] 在本研究中,我们开发了一种辅酶介导的超分子主客体半生物系统,该系统将人工和酶催化相结合,用于乙醇脱氢光催化析氢。 [7] 在此,通过超分子主客体相互作用构建了一种基于金属有机框架(MOFs)和超分子纳米阀的智能植物激素递送系统,即负载赤霉素(GA)的CLT6@PCN-Q,以调节双子叶大白菜的生长。和单子叶小麦。 [8] 它通过经典的“军士和士兵”机制突出二维手性诱导现象,其中诱导剂被整合到网络组件中,以及通过“超分子主客体”机制,其中诱导剂被困在多孔空间,导致违反直觉的手性反转。 [9] 金属有机框架 (MOF) 中的呼吸现象揭示了超分子主客体相互作用,这可能有利于许多工业应用中的化学分离。 [10] 因此,该研究证明了 VCD 光谱对类似超分子主客体复合物的表征的适用性。 [11] 为此,利用优化的超分子主客体(p-sulfonatocalix[4]arene-oxazine 1)报告对和 FMO3 催化体系来确定 XFZYD 中的生物活性化合物对 TMA 向 TMAO 转化的影响。 [12] 由于柱[5]芳烃/中性腈分子识别基序的超分子主客体相互作用,设计的分子可以自发自组装。 [13] 通过各种外部刺激的组合,这些荧光超分子主客体系统可以在 DMF/H2O (1:1, v/v) 溶液中揭示有趣的光致发光 (PL) 特性,包括 Al3+ 离子络合后的双荧光主客体系统, 一世。 [14] 在超分子主客体化学中准确测定超高结合亲和力是一项具有挑战性的工作,因为由于常见滴定方法的灵敏度限制,直接结合滴定通常限制在 <106 M-1 的亲和力。 [15] 结合亲和力和分子间相互作用是可用于理解超分子主客体系统中分子之间的分子识别的基本特征。 [16] 为此,我们利用氢键诱导的吩嗪衍生物(PY)和萘二胺(NDI)的自组装特性,成功地制造了一种基于超分子主客体相互作用的新型生物胺响应平台(P-N)。 [17] 热响应聚合物与超分子主客体相互作用的结合能够准确调节相变温度,同时还提供基于主客体络合的额外响应机制。 [18] 这些方式都进一步增加了超分子主客体系统的光化学和/或物理性质的多样性。 [19]
