  通过自适应宿主-客体相互作用选择性地逐步聚集一种新的荧光探针，用于硝化炸药的分化

  摘要：

  由于缺少芳香环和与荧光探针的相互作用较弱，很难检测出硝酸盐炸药。甚至更具挑战性的是，基于光诱导的电子转移或聚集引起的荧光变化机制，用多种硝酸盐炸药区分二硝酸盐。基于一种新策略-多个锚定芴二聚体8Py-2F的逐步聚集，设计了一种高选择性的硝酸盐炸药探针。与单体单体2Py-F相比，8Py-2F表现出选择性和逐步的荧光猝灭，从而可以爆炸出硝酸炸药-乙二醇（EGDN）和三乙二醇二硝酸酯（TEGDN）。TEGDN的检出限（LOD）为2.72 µM，EGDN的检出限为0.46 µM，比检测限低3个数量级。2PY-F。逐步淬灭过程与逐步聚集过程很好地匹配，如通过扫描电子显微镜（SEM）所证明的。核磁共振（NMR）和量子化学计算证明了亚硝酸盐与8Py-2F之间的相互作用力是氢键相互作用，并且相互作用距离远小于多种硝酸盐的相互作用距离，这归因于链的柔韧性和空间位阻，从而导致了自适应相互作用和更高的选择性。该

  Highly fluorescent intramolecular dimmers of two pyrenyl-substituted fluorenes bridged by 1,6-hexanyl: synthesis, spectroscopic, and self-organized properties

  摘要：

  Two intramolecular dimmers of 4-, 8-pyrenyl-substituted fluorenes budged by 1,6-hexanyl unit have been synthesized. They showed very strong fluorescent emission with the emission peak at around 450 nm and fluorescence efficiency as high as similar to 0 9. The absorption spectra also had high extinction coefficients. The cyclic voltammetric curves showed that they can be used as electron-donating materials. The DSC results suggested the dimmers have higher glass transition temperature. It was also found that these novel dimmers can self-organize into spherical particles from the solutions due to evaporation of the solvent. (C) 2010 Elsevier Ltd All rights reserved.

  of multiple anchored fluorene dimer 8Py-2F. Compared with its monomer counterpart 2Py-F, 8Py-2F showed a selective and stepwise fluorescence quenching to dinitrate explosives—ethylene glycol (EGDN) and triethylene glycol dinitrate (TEGDN). The limits of detection (LODs) are 2.72 µM for TEGDN and 0.46 µM for EGDN, which is three orders of magnitude lower than those of 2Py-F. The stepwise quenching process
