  微波辅助和环境友好的方法合成近红外荧光五甲胺花青染料

  摘要：

  开发了一种省时，环保的微波方法，并将其用于合成五甲胺花青染料及其相应前体的系统库。本文概述的合成从几天到几分钟极大地减少了五甲胺碳菁染料合成的反应途径，并且与常规加热方法（18-64％）相比，产率提高（89-98％）。通过微波辅助有机合成方法合成了十二个五次甲基花青染料实例，该化合物在快速的反应时间内提供了优异的收率，并使用简便的分离方法获得了该实例。此外，制备了三种具有新的亚甲基二氧基杂环结构的花青，与未取代的对应物相比，它们具有约40 nm的红移。

• Pentamethinium fluorescent probes: The impact of molecular structure on photophysical properties and subcellular localization

  The performance of fluorescent probes arises from their structural basis. In this study, we report design and synthesis of a series of novel symmetrical gamma-substituted pentamethinium fluorescent probes. Relationship between structure, photophysical properties and intracellular localization was explored and structural variations resulting in high photostabillity and selectivity for subcellular localization were obtained. Substitution of benzothiazolium moieties on both sides of the pentamethinium chain for indolium units led to red shift in the absorption and fluorescence emission maxima of the probe and increased photostability. The major advantage of the probes with side indolium units is their mitochondrial specificity, high photostability and synthetic accessibility. (C) 2014 Elsevier Ltd. All rights reserved.

  Compositions and methods for forming color images on a substrate capable of development at desired wavelengths or energy levels are disclosed and described. The color forming composition can include a carrier system and a latent pigment with a pendent group, wherein the latent pigment is colorless or pale in color while the pendent group is attached, and wherein the latent pigment is convertible to a colored pigment upon removal of the pendent group. Alternatively, the latent pigment can have multiple states of conjugation where the latent pigment is colorless or pale in a first conjugation state, and colored in a second conjugation state. The color forming compositions are useful in forming images on a wide variety of substrates, such as optical disks.

  An optical data recording medium (100) includes a substrate (220) and a markable coating including first and second layers (230, 232). The first layer (230) of the markable coating is established on the substrate (220) and includes a first predetermined ratio of a first absorber dye (239) and a first contrast-forming agent (240). The second layer (232) of the markable coating is established on the first layer (230) of the markable coating and includes a second predetermined ratio of a second absorber dye (239') and a second contrast-forming agent (240'). The second predetermined ratio is different from the first predetermined ratio.
