Click Assembly of 1,2,3‐Triazole‐Linked Dendrimers, Including Ferrocenyl Dendrimers, Which Sense Both Oxo Anions and Metal Cations

Clickety click: Click dendrimers, including the first click metallodendrimers, are synthesized in the presence of a stoichiometric amount of copper(I). The 1,2,3-triazolylferrocenyl dendrimers (see picture) are selective electrochemical sensors for both transition-metal cations and oxo anions.
