A novel dansyl-appended bile acid receptor for preferential recognition of Hg2+

Abstract

We have designed and synthesized a novel dansyl appended bile acid chemosensor using click chemistry. The chemosensor shows selective and efficient recognition of Hg²⁺ ions by forming a 1 : 1 complex with Hg²⁺ with a binding constant of 3.3 × 10⁴ M⁻¹. The limit of detection for Hg²⁺ was estimated to be 2 μM.
