Herein, a cysteine-functionalized derivative of TPE is presented as the first fluorescent organic dye for selective, label-free, sub-ppb level detection of As(3+) in aqueous media by taking the advantage of the aggregation induced emission feature. Besides, the first discrimination between the most toxic As(3+) and less toxic As(5+) was obtained.
