  具有不寻常头群拓扑结构的新型两亲物家族的合成和聚集特性

  摘要：

  已经合成了一个新的两亲物家族，它们源自具有不寻常拓扑结构的刚性二羧酸头基单元。这些分子在水溶液中的聚集已经通过 1 H NMR 和染料溶解方法进行了检查。两种聚集模式似乎在这组两亲分子中起作用，一种由头部决定，另一种由柔性尾部决定。当尾部很短或不存在时，前一种模式占优势，当尾部含有六个或更多非极性原子时，后者占优势。后一种模式看似是典型的胶束化过程，但前者的合作性较差

  A cationically curable composition for dental use containing a cationic polymerization initiator (I) and cationically polymerizable monomers (II), the cationically polymerizable monomers (II) containing an oxetane compound and an epoxy compound or an alkenyl ether compound at a ratio of amounts that satisfy the conditions expressed by the following formula,         (a x A) : (b x B) = 91 : 9 to 45 : 55    wherein A is a mol number of the oxetane compound, "a" is an average number of the oxetane functional group contained in one molecule of the oxetane compound, B is a mol number of the epoxy compound or the alkenyl ether compound, and "b" is an average number of the epoxy functional group contained in one molecule of the epoxy compound or an average number of the alkenyl ether functional group contained in one molecule of the alkenyl ether compound. The composition is not hindered by oxygen from being polymerized, cures quickly even without using a special polymerizable monomer or a particular polymerization initiator, little forms an unpolymerized layer on the surface even when polymerized and cured in a highly humid environment such as in the oral cavity, and is suited as a filling/restorative material for dental use.

  硫醚在医药和有机合成领域至关重要，但大多数合成烷基硫醚的方法都采用有恶臭的硫醇作为起始原料或产生副产物。另外，大多数硫醇对空气敏感，在大气条件下很容易氧化生成二硫化物；因此，需要一种新的硫醚合成方法。本文报道了一种简单、有效、绿色的方法，使用无味、稳定、低成本的ROCS2K作为硫醇替代物合成二烷基或烷基芳基硫醚衍生物。这种转化提供了广泛的底物范围和良好的官能团耐受性以及出色的选择性。该反应可能通过黄原酸酯中间体进行，黄原酸酯中间体可以通过在无过渡金属和无碱条件下用 ROCS2K 亲核取代烷基卤或芳基卤轻松生成。
• Silver Ion Selective Fluoroionophores Based on Anthracene-Linked Polythiazaalkane or Polythiaalkane Derivatives

  A dozen novel fluoroionophores have been synthesized which are polythiazaalkane and polythiaalkane derivatives coupled with an anthracene moiety by methyl, carbonyl, or methylphenylene bridging groups. The protonation and metal ion complexation behavior of analogues were examined in 1,4-dioxane--water solutions spectrophotometrically and spectrophotofluorometrically. The fluoroionophores, 1, 2, 5, and 6 contain basic nitrogen atoms and quench the fluorescence in the free forms because of photoinduced electron transfer (PET) from a nitrogen atom to a photoexcited anthracene unit. The fluorescence was recovered by the protonation on the nitrogen atom. The fluorescence intensities of the other fluoroionophores used here were not dependent on the pH of the solution. On the complexation of the protonated fluoroionophores 1, 2, 5, and 6 with metal ions under the acidic condition, the fluorescence intensities were decreased by the addition of silver ion selectively. Under the same conditions, the other fluoroionophores exhibited a decrease of the fluorescence intensity with the addition of silver ion selectively. These results imply that the fluoroionophores could form complexes and release a proton from the nitrogen atom of the protonated fluoroionophores. The quenching of the fluorescence of the complexed fluoroionophores 3, 4, 7, and 8-12 could be caused by the interaction of a silver ion with a ct-electron of the anthracene unit. The degree of spectral change on the complexation with silver ion is primarily dependent on the strength of the interaction of the bound silver ion with nitrogen atom, far 1, 2, 5, and 6, or with a pi-electron of the anthracene unit, for 3, 4, 7, and 8-12.
