    折叠的短氮杂肽用于基于构象转换的荧光传感
    摘要:
    本文中,我们报告了一种基于构象转换的荧光传感方案,该方案使用了包含折叠的β-turn结构的基于二肽的酰胺基硫脲(氮杂肽)。酰胺基硫脲在其两个末端配备了一个电子受体和一个电子供体或两个荧光团,因此由于两个末端紧密靠近的转弯结构,它显示出增强的激基复合物或受激准分子发射;另一方面,由于阴离子结合复合物的最终扩展构象,它在阴离子与硫脲部分结合时显示出显着的比例荧光响应。

  • Elucidating sensing mechanisms of a pyrene excimer-based calix[4]arene for ratiometric detection of Hg(<scp>ii</scp>) and Ag(<scp>i</scp>) and chemosensor behaviour as INHIBITION or IMPLICATION logic gates

    This article reports the synthesis and characterisation of two lower rim calix[4]arene derivatives with thiourea as spacer and pyrene or methylene–pyrene as fluorophore. Both derivatives exhibit a fluorimetric response towards Hg2+, Ag+ and Cu2+. Only methylene–pyrenyl derivative 2 allows for selective detection of Hg2+ and Ag+ by enhancement or decrease of excimer emission, respectively. The limits
    本文报道了两种下缘杯[4]芳烃衍生物的合成和表征,其中硫脲作为间隔物,芘或亚甲基芘作为荧光团。两种衍生物都表现出对 Hg 2+、Ag +和 Cu 2+的荧光响应。只有亚甲基-芘基衍生物2允许分别通过增强或减少准分子发射来选择性检测 Hg 2+和 Ag + 。2的检测限为8.11 nM (Hg 2+ ) 和 2.09 nM (Ag +)。进行了 DFT 和 TD-DFT 计算研究,并用于确定解释荧光滴定期间观察到的响应的可能结合模式。计算表明存在不同的结合位点,具体取决于2的构象,这为荧光的非线性变化提供了合理的解释,具体取决于金属中心和构象异构体之间相互作用的物理性质。还生成了抑制和暗示逻辑门,分别监测芘单体 (395 nm) 和准分子 (472 nm) 发射的信号输出。因此,2是一个潜在的主要传感器,朝向 Ag +和 Hg 2+能够配置两种不同的逻辑门操作。

  • Introduction of a Disulfide Bond as a Key Element of Acyclic Bis-Thiourea-Type Anion Receptors
    作者:Kentaro Tomita、Toshio Ishioka、Akira Harata
    DOI:10.1246/bcsj.20130267
    日期:2014.3.15
    This article shows that a difference in the building blocks of the molecular framework, C–C to S–S, results in a significant influence on its optical properties. Acyclic anion receptors, bis2-[3-(substituted)thioureido]ethyl} disulfides were newly synthesized, and their optical properties in response to complex formation with an acetate ion were compared with those of a hexamethylene framework between two thioureido groups. Quantum chemical calculations suggested that receptors fold their molecular framework around disulfide because of the presence of the intramolecular hydrogen bonding between two N,N′-disubstituted thioureas. The complex of the receptor and the acetate ion with 1:1 stoichiometry consists of the coordination of two thioureido groups to the acetate via hydrogen bonds. This complex formation is accompanied by a dissociation of intramolecular hydrogen bonding and rotation of one side of the thioureido group. These circumstances of conformational changes in the molecular framework functioned by switching on and off the excimer fluorescence of the 1-pyrenylmethyl derivative.
    本文表明,分子框架的组成部分(C-C 到 S-S)的差异对其光学性质产生重大影响。新合成了无环阴离子受体双2-[3-(取代)硫脲基]乙基}二硫化物,并将其响应与乙酸根离子形成络合物的光学性质与两个硫脲基之间的六亚甲基骨架的光学性质进行了比较。量子化学计算表明,由于两个 N,N'-二取代硫脲之间存在分子内氢键,受体将其分子框架折叠在二硫键周围。受体和乙酸根离子按 1:1 化学计量形成的复合物由两个硫脲基通过氢键与乙酸根配位组成。这种复合物的形成伴随着分子内氢键的解离和硫脲基一侧的旋转。分子框架中构象变化的这些情况通过打开和关闭 1-芘基甲基衍生物的准分子荧光来发挥作用。

    An Hg2+‐selective fluorescent sensor (1) bearing pyrene as a fluorophore was synthesized. A sandwich‐stacking binding mode was formed during the binding process, which increased the excimer fluorescence 22‐fold at 490 nm. Compound 1 was successfully applied in in vivo imaging to trace the enrichment and distribution of mercury in the nervous system, digestive system, and reproductive system of Caenorhabditis

Interestingly, both 1 and 2 exhibited an exclusive fluorescence sensing of F over other anions, with the fluorescence of the receptors showing a turn-off response. Further, the binding mechanism between receptors and anions was confirmed by 1 H NMR titrations, which reveal that the two thiourea NH donors
