Abstract

Histidine-dialkoxyanthracene (HDA) was synthesised as a turn off type fluorescent sensor for fast and sensitive detection of mercury ions (Hg²⁺) in aqueous media. The two histidine moieties act as ‘claws’ to selectively complex Hg²⁺. The binding ratio of HDA to Hg²⁺ was 1:1 (metal-to-ligand ratio). The association constant for Hg²⁺ towards the receptor HDA obtained from Benesi–Hildebrand plot was found to be 3.22 × 10⁴ M⁻¹ with detection limit as low as 4.7 nM (0.94 μg/L).
