  • Copper-catalyzed selective difunctionalization of N-heteroarenes through a halogen atom transfer radical process

    A highly regioselective Cu-catalyzed difunctionalization of different N-heteroarene salts such as quinolinium and benzothiazolim salts was developed with ether and X− (X = Br, Cl) as the halogen source under mild conditions. This transformation involved the combination of oxidative coupling, selective free radical resonance and a copper-catalyzed halogen atom-transfer radical process. The regiochemistry

    Based on the frequently-used cyanine dye probe thiazole orange (TO), a novel kind of cyanine dye was designed and synthesized. Carbazole was inserted into the methylidyne structure of TO as a bridge to afford a kind of novel styryl cyanine dye with carbazole bridged chain. The dyes were characterized by HNMR and MS. The spectra of the novel dyes were also studied and the results showed that the fluorescent wavelength of novel carbzole dye shifted red for 100 nm, stock shift increased by 70 nm and the fluorescent intensity enhanced by 70 times compared to that of TO. When the novel dye was labeled by BSA, its fluorescent wavelength changed little and the intensity enhanced. It is indicated that it can be used as an excellent fluorescent probe in biological labeling.
    在常用的氰基染料探针噻唑橙(TO)的基础上,设计并合成了一种新型氰基染料。将咔唑作为桥插入 TO 的甲基idyne 结构中,得到了一种新型的咔唑桥链苯乙烯基氰基染料。这些染料通过 HNMR 和 MS 进行了表征。对新型染料的光谱也进行了研究,结果表明,新型咔唑染料的荧光波长红移了 100  nm,与 TO 相比,股移增加了 70  nm,荧光强度增强了 70 倍。当新型染料被 BSA 标记后,其荧光波长变化不大,荧光强度增强。这表明它可以作为一种优良的荧光探针用于生物标记。

In addition, morphological inspection demonstrates that the morphology of the aggregated form of Cya‐PDI molecules changed from plate‐shaped to rod‐like aggregates under the co‐effects of time and water. An edge‐to‐face arrangement of aggregation was proposed and discussed. The fact that the Cya‐PDI aggregates show a

  • Assembly of New Merocyanine Chromophores with a 1,8-Naphthalimide Core by a New Method for the Synthesis of the Methine Function

    A new method for the synthesis of the monomethine group using nitro as a leaving group in an SN-Ar reaction is described. A series of novel merocyanine dyes has been synthesised and their photophysical properties have been elucidated. The longest wavelength absorption occurs in the range 519–619 nm and the molar absorptivities vary with the substituents and are in the range 1000–47700 L mol–1 cm–1. The dyes show high chemical and photostability. One example from the series has the ability to distinguish methanol from ethanol. The introduction of a quinoid fragment into the structure leads to a pronounced intramolecular charge transfer and hence a noticeable positive solvatochromism. The structures and electronic properties of the compounds have been studied by density functional theory (DFT) and time-dependent DFT.

    介绍了一种在 SN-Ar 反应中使用硝基作为离去基团合成单甲基的新方法。合成了一系列新型美拉尼菁染料,并阐明了它们的光物理特性。最长波长的吸收发生在 519-619 nm 范围内,摩尔吸收率随取代基的不同而变化,范围在 1000-47700 L mol-1 cm-1 之间。这些染料具有很高的化学稳定性和光稳定性。该系列中的一个例子能够区分甲醇和乙醇。在结构上引入一个醌片段会导致明显的分子内电荷转移,从而产生明显的正溶解色度。这些化合物的结构和电子特性已通过密度泛函理论(DFT)和随时间变化的 DFT 进行了研究。

    10-5 M in CH2Cl2, the resultant Langmuir-Blodgett (LB) films are purple, λmax 563 ± 3 nm. They have an optimum effective second-order non-linear optical susceptibility of 75 pm V-1 at 1.064 μm and, when sandwiched between gold electrodes, exhibit asymmetric current-voltage curves, characteristic of molecular rectification. In contrast, when spread at slightly higher concentrations (e.g. 10-4 M), the
