Hydrazine (N2H4) is one of the commonly used chemical reagents in numerous industries and applications but its toxicity to humans poses a need to develop simple visual detection methods. Herein, we demonstrate a novel dual-mode system to detect and simultaneously consume hydrazine in vapour and solution by using a small photoresponsive molecule that has altered optical response (both colourimetric
肼(N 2 H 4)是众多行业和应用中常用的化学试剂之一,但其对人体的毒性需要开发简单的视觉检测方法。在此,我们展示了一种新颖的双模式系统,通过使用与肼反应后光学响应(比色和荧光)发生改变的小光响应分子来检测并同时消耗蒸气和溶液中的肼。

thereby enables the assembly of a new combination of aryl moieties around the reformed ethylene bridge. The reversible C═C double bond exchange has exemplarily been investigated using α-cyanostilbenes. Establishing a dynamic equilibrium reaction from α-cyanodiarylethene with arylacetonitriles under mild conditions has been the basis to access constitutional libraries of new photoswitches with potentially
