Sulfur dioxide gas detection by reversible _1-SO2-Pt bond formation as a novel application for functionalised metallo-dendrimers

Abstract

Multimetallics such as dendrimer 3 which are functionalised at their periphery with platinum(II) metal centres reversibly absorb SO2 to yield macromolecules with significantly enhanced solubility characteristics and drastic colour changes; properties which make these compounds highly active sensors for milligram quantities of toxic SO2 gas.
