  Colorimetric anion sensing by polyamide models containing urea-binding sites

  摘要：

  Novel colorimetric polyamide model compounds for anion-sensing applications are described. Light beige solutions of one of the models (M3) in DMSO develop a red to yellow-reddish colour upon addition of some anions, including OH-, F-, HC[image omitted], P[image omitted], AcO-, benzoate-, oxalate2- and p-toluenesulphonate-. In contrast, they remain unchanged in the presence of CH2ClC[image omitted], H2P[image omitted], CF3CO2-, Br-, methanesulphonate-, Cl- or I-. The reddish colour caused by the addition of basic anions is due to the deprotonation of the urea groups, while the yellowish colour corresponds to the modification of the electron density surrounding the urea group due to complexation. The development of the yellow colour of DMSO solutions of M3 upon addition of acetate ions and the disappearance of the red colour of solutions of M3/fluoride by the displacement of acetate ions can serve as a novel colorimetric assay for the titration of the acetate anion, with detection limits close to 1ppb. The host:guest stoichiometry (polyamide model compound:anion complexes) and the stability constants of complexes were determined by 1H NMR.

  A focused library of potential hydrogelators each containing two substituted aromatic residues separated by a urea or thiourea linkage have been synthesised and characterized. Six of these novel compounds are highly efficient hydrogelators, forming gels in aqueous solution at low concentrations (0.03–0.60 wt %). Gels were formed through a pH switching methodology, by acidification of a basic solution

  已合成和表征了潜在的水凝胶剂的聚焦库，每个均包含两个被尿素或硫脲键隔开的取代的芳族残基。这些新颖的化合物中有六个是高效的水凝剂，可在水溶液中以低浓度（0.03-0.60 wt％）形成凝胶。凝胶是通过pH转换方法，通过添加HCl或将葡萄糖酸δ-内酯缓慢水解来酸化碱性溶液（pH 14至≈4）而形成的。通常，胶凝过程伴随着胶凝剂吸收光谱的急剧变化，导致颜色发生显着变化，通常从鲜橙色变为浅黄色。每种凝胶都能够从水溶液中螯合大量的芳香族阳离子染料亚甲基蓝（最高至1。每克干胶凝剂含02克染料）。其中两种凝胶的低温透射电子显微镜显示了高纵横比纤维的广泛网络。纤维的结构在添加20wt％的染料时发生显着改变，导致聚集并显着缩短了原纤维。这项研究证明了这些新型凝胶作为廉价，有效的水净化平台的可行性。
