Quadruple-Channel Sensing:A Molecular Sensor with a Single Type of Receptor Site for Selective and Quantitative Multi-Ion Analysis

摘要

Highly selective cation or anion sensing is imperative for many areas of technology,including environmental,biological,clinical,and waste management applications.For heavy-and transition-metal ions (e.g.Pb~(2+),Cd~(2+),and Hg~(2+);Cu~(2+) and Fe~(3+)),selective sensory protocols are particularly critical owing to their high toxicity and crucial role in biological systems.
