  调节基于二氰基异佛尔酮的荧光团的供体，用 NIR 荧光检测人血清白蛋白

  摘要：

  由于真实血清和尿液中内源性物质的短波长荧光的干扰，迫切需要开发用于检测人血清白蛋白（HSA）的NIR荧光探针。然而，以前的大多数报告都位于短波长区域 (< 600 nm)。在这项工作中，一系列dicyanoisophorone的（DCO）为基础的荧光1 - 4与不同的捐助团体已设计和调查。已经对其光物理特性进行了系统研究。在这些探针中，有4 种表现出 NIR 发射，具有最高的荧光亮度和对 HSA 最敏感的信号响应。进一步的研究表明，4可以以 1:1 的比例强力结合到 HSA 的 DS1 口袋中。重要的是，基于4的方法已被证明能够检测真实血清和尿液样本中的 HSA。

  utilized in various fluorescence imaging techniques. However, many existing modification strategies could not balance the performance (such as brightness, photostability, water solubility, and permeability) of fluorophores. Herein we report a general strategy to enhance the performance of donor–acceptor-type fluorophores by introducing azetidine-containing heterospirocycles to the commonly used fluorophore

  荧光染料广泛用于各种荧光成像技术中。但是，许多现有的修饰策略无法平衡荧光团的性能（例如亮度，光稳定性，水溶性和渗透性）。本文中，我们报告了通过将含氮杂环丁烷的杂螺环引入常用的荧光支架中来增强供体-受体型荧光团性能的一般策略。事实证明，这种策略是开发高质量荧光团的一般方法。

• Synthesis and fluorescence of dicyanoisophorone derivatives

  A class of dicyanoisophorone derivatives 1-5 with electron-donating groups has been prepared by a two-step condensation reaction. Fluorescence both in solution and in pure solid state are measured. It is found that dicyanoisophorone derivatives 1-5 exhibit fluorescence in both solution and pure solid state. An enhancement of fluorescence in solid state probably results from the aggregation-induced emission. It is also found that dicyanoisophorone derivatives 1-5 show large Stoke's shifts in solution as well as in pure solid state. The origin of fluorescence of dicyanoisophorone derivatives depends on the nature of substituents, with a strong push pull chromophores dicyanoisophorone system, red or orange solid-state fluorescence is obtained.

  日期：2015.2

  Dicyanoisophorone derivatives (1-3), which contain a strong push pull chromophores system, have beep prepared by a two-step condensation reaction, and their fluorescence in solution, polymeric thin film and pure solid state are measured. It is found that 1-3 exhibit no or weak fluorescence in both solution and pure solid state, but strong red fluorescence in polymeric thin film. Mechanism study implies that the enhanced fluorescence of 1-3 in polymeric thin film results from the restriction of intramolecular vibrational and rotational motions. In addition, it is also found that the polarity of polymeric matrix has influence over the fluorescence of dicyanoisophorone derivatives, using PMMA as polymeric matrix, a fluorescent thin film with a strong red emission is obtained.
