摘要

A new indole-based fluorescent chemosensor 1 was prepared and its metal ion sensing properties were investigated. It exhibits high sensitivity and selectivity toward Hg ²⁺ among a series of metal ions in H ₂O-EtOH (7:1, v/v). The association constant of the 1:1 complex formation for 1-Hg ²⁺ was calculated to be 9.57 × 10 ³ M ^-1, and the detection limit for Hg ²⁺ was found to be 2.25 × 10 ^-5 M. Computational results revealed that 1 and Hg ²⁺ ion formed with a central tetrahedron-coordinated Hg ²⁺.
