Description
Summary:[Display omitted] •A TPE derivative has been synthetized as a selective quimiodosimeter to nitric oxide detection.•The transduction mechanism is based on the (AIE) phenomena through a “click reaction” catalyzed by NO.•The detection limit is 15 ppm and no changes are induced by other gases. 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).
