However in DMSO : water (2 : 1) solution it responds selectively to CN− ion. The probe with a phenol unit is highly selective and sensitive for CN− and can be used for naked eye, semiquantitative sensing of CN− ion in DMSO : water (2 : 1) solution. The chemodosimetry has been attributed to the acid catalyzed Strecker's reaction of an imine bond and is being reported for the first time in a Schiff's
二 均三甲苯 基于探针,具有 儿茶酚已经合成了与席夫碱结合的对-苯酚单元。用邻苯二酚单元的探针,可以使用至F之间有义和判别-和CN -通过使用不同的比色和荧光响应二甲基亚砜作为溶剂。但是在二甲基亚砜 : 水(2:1)溶液它选择性地响应CN -离子。与酚单元的探针具有高度选择性和CN敏感-和可以用于肉眼,CN的半定量检测-离子在二甲基亚砜 : 水(2:1)解决方案。化学计量学归因于酸催化的亚胺键的斯特雷克反应,并且首次在席夫碱中报道。
