TPE‐TCF, a simple TPE‐derivative with red‐emission was used to detect cyanide in the condition of single dispersion as well as under aggregate state. It could be found that TPE‐TCF exhibited excellent fluorescent response to cyanide in both situations, and the mechanism was supposed to be the reaction between cyanide and the double bond in TPE‐TCF as well as the aggregation induced emission property of the reacted TPE‐TCF molecules. What's more, TPE‐TCF could distinguish cyanide with other species, such as common anions and biotiol well, which indicated it as a potential indicator for cyanide with good selectivity and specificity.
