在2中的三氟乙酰氨基基团上亲核的氰化物加成会产生两亲性物质，这将诱导silole 1聚集，因此，该系综的荧光大大增加。因此，可以用硅孔1和化合物2的系综建立水溶液中氰化物的荧光开启检测。同时，该体系对氰化物的选择性优于其他常见的无机阴离子。
The nucleophilic addition of cyanide to the trifluoroacetylamino group in 2 yields an amphiphilic species which would induce the aggregation of silole 1, and as a result, the fluorescence of the ensemble increases largely. Accordingly, a fluorescence turn-on detection of cyanide in aqueous solution can be established with the ensemble of silole 1 and compound 2. Also, this ensemble displays good selectivity toward cyanide over other common inorganic anions.
