Abstract
Strain-promoted oxidation-controlled cyclooctyne-1,2-quinone cycloaddition (SPOCQ) between functionalized bicyclo[6.1.0]non-4-yne (BCN) and surface-bound quinones revealed an unprecedented 100% conjugation efficiency. In addition, monitoring by direct analysis in real time mass spectrometry (DART-MS) revealed the underlying kinetics and activation parameters of this immobilization process in dependence on its microenvironment.
