  摘要：

  专为淋巴图技术量身定制的光学分子成像造影剂，可在癌症的计划和手术治疗中实施近红外（NIR）荧光图像引导的导航，将大大有助于实现潜在转移性肿瘤引流的实时可视化淋巴结需要进行手术活检和/或切除，从而确保不遗漏的疾病，以防止复发并提高患者存活率。在此，描述了为克服通常用于此类应用的通用分子荧光染料的次优性能而产生的局限性而开发的第一种NIR荧光rosol染料（THQ-Rosol）的开发。在开发THQ-Rosol，我们根据密度泛函理论（DFT）计算，制备了一系列渐进式扭转限制性N-取代的非NIR荧光rosol染料，其中我们辨别了它们的计算能量，建模的N–C3'扭转角和评估的性能之间的高度相关性。我们利用这些牢固的关系合理设计THQ-罗斯洛，其中DFT计算启发一种创新的方法和合成策略，得到不带电荷的呫吨基芯的支架/分子平台与恰当地升高p ķ一个沿着NIR荧光发射值（ca.700 –900 nm）。THQ-Rosol表现出710

• Photo-Fenton degradation of malachite green catalyzed by aromatic compounds under visible light irradiation
  作者：Feng Chen、Jianjun He、Jincai Zhao、Jimmy C. Yu

  DOI：10.1039/b107404k

  日期：2002.3.11

  The photo-Fenton degradation of malachite green (MG) catalyzed by aromatic derivatives under visible light irradiation was examined. Aromatic derivatives exhibit significant catalytic action in the photo-Fenton reaction. The degradation rates of MG with various kinds of aromatic derivatives obey the following order: hydroquinone > salicylic acid > quinone > carboxylic aromatic derivatives > amido aromatic derivatives. GC-MS detection of the products formed in the MG Fenton degradation in the presence of aromatic derivatives shows that the addition of the latter does not change the MG degradation pathways, although it greatly alters the reaction rate. The MG degradation mainly involves two different pathways: cleavage with a [MG–OH]˙ transition intermediate and N-demethylation.

  在可见光照射下，研究了芳香衍生物催化下的光芬顿法降解孔雀石绿（MG）。芳香衍生物在光芬顿反应中表现出显著的催化作用。各种芳香衍生物对MG的降解速率遵循以下顺序：对苯二醇 > 水杨酸 > 醌 > 羧基芳香衍生物 > 酰胺芳香衍生物。GC-MS检测显示，在芳香衍生物存在的情况下，MG芬顿降解生成的产物表明，后者的加入并未改变MG的降解路径，尽管大大改变了反应速率。MG的降解主要涉及两种不同的途径：通过[MG–OH]˙过渡中间体的裂解和N-去甲基化。
