Abstract Fluorescence sensors for complicated molecules such as pesticides were paid much attention lately due to the merits of simple operation, high sensitivity and selectivity, in‐situ detection. In this work, a novel fluorescent sensor pesticide starane was prepared based on imidazolium‐decorated bis‐cyanostilbene macrocycle ( IBM ). exhibited obvious “turn‐on” fluorescence change from dark blue‐green bright blue after sensing with selectivity among 28 kinds guests. The detecting limitation low 0.011 μM, which lowest one in literatures. mechanism confirmed that located cavity molecular interaction multiple hydrogen bonds, π‐π stacking hydrophobic interaction. application experiments suggested examined well test paper good quantitatively detected water samples, implying real‐time potential real environment daily life.
