An Aggregation Induced Emission (AIE) transduction mechanism has been used to detect nitric oxide (NO). A new tetraphenylethylene derivative functionalized with alkyne moieties has been prepared to work as a fluorescent probe. A “click” reaction was chosen because NO is able to generate the required catalytic species by reducing Cu(II) to Cu(I).

一氧化氮诱导的“喀哒”反应触发四苯乙烯衍生物的聚集诱导发射（AIE）现象：一种新型的NO荧光探针

聚集诱导排放（AIE）转导机制已用于检测一氧化氮（NO）。已经准备了用炔基部分官能化的新的四苯基乙烯衍生物，以用作荧光探针。选择“点击”反应是因为NO能够通过将Cu（II）还原为Cu（I）来生成所需的催化物质。
