Portable fluorescent conjugated microporous polymer sensor coupled with a smartphone for on-site Fe3+ detection in water
Abstract
A novel conjugated microporous polymer (THDH-DMA) was synthesized as a highly selective and sensitive “turn-off” fluorescent sensor for Fe³⁺ in water, showing rapid response and a low detection limit. A smartphone-integrated test strip enabled on-site, real-time detection of Fe³⁺ in water for practical water quality monitoring.
