A new naphthopyran-based chemodosimeter with aggregation-induced emission: selective dual-channel detection of cyanide ion in aqueous medium and test strips

•Novel probe NPM was synthesized and characterized.•NPM exhibits both AIE and ICT characteristics.•CN− selectively quenched green fluorescence of NPM in aqueous medium.•The CN−induced color change of DPM can be visualized by the naked eye.•Test strips were fabricated for detecting CN− in water samples.
