| Abstract: |
A terminalalkyne is immobilized rapidly into a full monolayer by squishing asmall volume of a solution of the alkyne between an azide-modifiedsurface and a copper plate. The monolayer is covalently attached tothe surface through a copper-catalyzed alkyne–azide cycloaddition(CuAAC) reaction, and the coverages of the immobilized electroactivealkyne species are quantified by cyclic voltammetry. A reaction timeof less than 20 s is possible with no other reagents required. Theprocedure is effective under aerobic conditions using either an aqueousor aprotic organic solution of the alkyne (1–100 mM). [ABSTRACT FROM AUTHOR] |
