detection of a wide range of primary and secondary amines. The probes consist of aldehyde‐ or ketone‐substituted diarylethenes, which undergo an amine‐induced decoloration reaction, selectively to give the ring‐closed isomer. Thus, these probes can be activated at the desired moment by light irradiation, with a sensitivity that allows the detection of amines at concentrations as low as 10−6 m in solution
我们的新型,简单且准确的比色法基于二芳烃(DAE),可快速检测多种伯胺和仲胺。探针由醛或酮取代的二芳烃组成,它们经过胺诱导的脱色反应,选择性地产生闭环异构体。因此,可以通过光照射在期望的时刻激活这些探针,其灵敏度使得可以检测溶液中浓度低至10 -6 m的胺。另外,将DAE实际固定在纸上可以在30秒内检测出高于12 ppbv阈值的气相中的生物胺,例如尸胺。
