Abstract

A novel sensitive and specific Hg²⁺ chemodosimeter, derived from 1′,3′-dithiane-substituted 2,1,3-benzoxadiazole, displays “turn-on” fluorescent and colorimetric responses via an Hg²⁺-triggered aldehyde recovery reaction. Its potential to monitor Hg²⁺ in living organisms has been demonstrated using zebrafish larvae.
