Abstract

A novel metal-organic framework of RuUiO-67 was successfully fabricated and exploited as a chemical sensor for the colorimetric detection of Hg2+. The chromophoric Ru complex in RuUiO-67 was designed as a Hg2+ recognition site and a signal reporter. The elaborated probe exhibited a rapid colorimetric response, high selectivity, and sub-micromolar sensitivity for Hg2+ detection.
