A new hydrazine probe was designed, which demonstrates ultrafast “turn-on” response towards hydrazine both in solution and as gas, due to the excellent AIE (aggregation-induced emission) characteristic of the yielded products. Excitedly, the corresponding fabricated test strips can report the presence of tracehydrazine as low as 10 nmol/L in aqueous medium in seconds conveniently, with very high selectivity
