Aggregation-induced emission (AIE)-active N-arylated ferrocenyl pyrazole chromophores: second-order nonlinear optical and turn on/off fluorescence for the detection of picric acid in mixed aqueous media

AIE-active N -arylated ferrocenyl pyrazoles show SHG efficiencies and used as highly selective and sensitive fluorescent sensors for the detection of picric acid in mixed aqueous media.
