  用于有机磷神经毒剂模拟物的荧光传感器

  摘要：

  我们提出了一种小分子传感器，可对含有有机磷 (OP) 的神经毒剂模拟物的存在提供光学响应。该设计包含三个关键特征：伯醇、靠近醇的叔胺和用作光学读数的荧光基团。在传感器的静止状态下，碱性胺的孤对电子通过光诱导电子转移 (PET) 淬灭附近荧光团的荧光。暴露于 OP 神经毒剂模拟物会触发伯醇的磷酸化，然后随着胺取代产生的磷酸盐迅速发生分子内取代反应。这种环化反应生成的季铵盐不再具有孤对电子，

  聚（甲基丙烯酸烷基酯）的温度和烷基对on客体分子激发单线态的分子间和分子内相互作用的影响

  摘要：

  温度引起的pyr和N，N荧光的静态和动态特性变化-二甲基-3-（吡喃-1-基）丙-1-胺（PyC3NMe2）已用于确定由5种聚甲基丙烯酸烷基酯（PAMA）聚合物薄膜提供的各向异性环境中这些探针的位置和迁移率其中烷基是乙基，丁基，异丁基，环己基和十六烷基。from的发射报告了客体位点的极性以及分子在位点之间平移扩散的能力，而PyC3NMe2的发射则产生了有关客体位点的流动性和形状的信息。已从20到> 400 K获得数据，该范围跨越宿主体内数个松弛过程的开始。这些数据表明the烯基在大多数PAMA中位于酯官能团附近，尽管与它们（和主链）的距离取决于烷基的体积。这项研究得出的最重要的结论之一是，探针分子附近的节段弛豫现象的发生率（而不是自由体积（如先前从聚乙烯薄膜中的荧光测量得出的结论））是导致荧光变化的主要因素。实际上重要的是，这些速率的变化已允许定位在探针附近发生的许多松弛现象的开始温度。

• Interaction of hydrophobic probes with serum albumin - influence of the side chain and exciplex formation at the binding site

  Novel fluorescent probes of the generic formula Ar-(CH2)(n)-NH3+ (Scheme I, Ar = 9-anthryl or 3-pyrenyl) were synthesized, and their binding properties with bovine serum albumin (BSA) have been evaluated. The anthryl probes 9-anthrylmethylamine hydrochloride (AMAC), N-ethyl(9-anthryl)methylamine hydrochloride (N-Et-AMAC),and 3-(9-anthryl)propylamine hydrochloride (APAC) showed small changes in their absorption spectra upon binding to BSA, whereas the pyrenyl analog, 4-(1-pyrenyl)butylamine hydrochloride (PBAC), showed a 5-nm red shift and an increase in the extinction coefficient at the peak positions. Such a red shift and increase in the intensity of the absorption transitions are consistent with binding of PBAC to hydrophobic sites on the protein. The fluorescence spectra of the anthryl and pyrenyl analogs exhibit different trends. The anthryl analog emission was quenched very effectively by increasing amounts of BSA (K-sv similar to 2.6 X 10(3) M(-1)). In contrast, PBAC emission was quenched at low BSA concentration whereas at higher concentrations of the protein the emission was enhanced. The fluorescence decays of the anthryl probes bound to the protein can be described by a short-lived and a long-lived component (10.6 and 6.7 ns for AMAC, 10.3 and 5.1 ns for APAC, 14.6 and 7.8 ns for N-Et-AMAC) indicative of at least two types of binding sites. In the case of PBAC, a third component was observed at probe:protein ratios higher than 1:5, which may be due to an exciplex formed at the binding site. Data from the equilibrium dialysis experiments indicate that the order of protein binding affinity of these probes is PBAC >> APAC > N-Et-AMAC > AMAC. Steady-state and time-resolved fluorescence quenching experiments with potassium iodide confirmed the above trend in the binding affinities. Upon binding to BSA, APAC and PBAC emission was extensively protected whereas only moderate protection has been observed for N-Et-AMAC and AMAC. A comparison of the binding properties of AMAC and N-Et-AMAC shows that increased distance of separation between the hydrophobic moiety and the cationic function enhances the protein binding affinity. Additionally, comparison of APAC with PBAC revealed the strong role of hydrophobic groups in the binding interactions. Therefore, the protein binding affinity of these probes depends on the degree of hydrophobicity of the aromatic moiety and on the length of the linker separating the hydrophobic group the cationic function.

  A set of modular components was designed, synthesized, and combined to yield an innovative, robust, and reliable methodology for the self-assembly of large supramolecular structures on silicon wafers. Specific host-guest and H-bonding motifs were embedded in a single molecule by exploiting the remarkable complexing properties of tetraphosphonate cavitands toward methylammonium and methylpyridinium salts and the outstanding homo- and hetero-dimerization capability of the ureidopyrimidone moiety. An assembly/disassembly sequence in solution was devised to assess the orthogonality and reversibility of H-bonding and host-guest interactions. The entire process was fully tested and characterized in solution and then successfully transferred to the solid state. The selected binding motifs resulted to be fully compatible in the assembly mode and individually addressable in the disassembly mode. The complete orthogonality of the two interactions allows the molecular level control of each step of the solid-state assembly and the predictable response to precise external stimuli. Complementary surface analysis techniques, such as atomic force microscopy (AFM), ellipsometry, and fluorescence, provided the univocal characterization of the realized structures in the solid state.
