  摘要：

  对环芳烷 (CP44) 和 β-环糊精 (β-CD) 与几种苯胺萘磺酸 (ANS) 的包合络合物已通过包含时荧光光谱的增强来表征。β-CD 和 CP44 与 ANSs 形成 1:1 的包合物，证明了后者包合物的高稳定性。从夹杂常数的温度依赖性（范特霍夫分析）观察到的热力学参数表明，CP44 与 ANS 的夹杂络合是焓驱动的。此外，基于 1H-和 2D ROESY-NMR 测量讨论了包合物的结构。发现CP44封装了ANS的萘部分。另一方面，观察到 4-OH 取代的 ANS 的 β-CD 包合物结构存在差异。与 CP44 相比，发现包含 β-CD 的分子识别更敏感。此外，使用 ANS 作为荧光探针评估了 CP44 和 β-CD 腔内的局部极性。基于这些结果，我们认为 CP44 和 β-CD 疏水腔中 ANS 的局部极性在包含后量子产率提高中起重要作用。

  Bis-azo colorants for use as bluing agents, laundry care compositions including bis-azo colorants that may serve as bluing agents, processes for making such bluing agents and laundry care compositions and methods of using the same. The bluing agents are generally include at least two components: at least one chromophore component and at least one polymeric component. These bluing agents are advantageous in providing a whitening effect to fabrics, while not building up over time and causing undesirable blue discoloration to the treated fabrics.

• Thermodynamic study on the effects of .beta.-cyclodextrin inclusion with anilinonaphthalenesulfonates

  DOI：10.1021/ac00183a024

  日期：1989.4.15

  Thermodynamic parameters and stoichiometries for the binding of anilinonaphthalenesulfonates to beta-cyclodextrin are obtained from steady-state fluorescence intensity and anisotropy measurements. Specifically, formation constant, enthalpy, and entropy values are obtained for complexes of beta-cyclodextrin with eight different substrate molecules at five different temperatures and six different pH values, and their associated errors are given. We propose an explanation of the relative magnitudes of the values obtained with regard to the geometry of the substrate and the importance of the various noncovalent interactions responsible for the complexation.
