In-situ nanospectroscopic imaging of plasmon-induced two-dimensional [4+4]-cycloaddition polymerization on Au(111)

Abstract

Here, the authors use tip-enhanced Raman spectroscopy for in-situ investigation of plasmon-induced [4+4]-cycloaddition polymerization on Au(111). They find that this occurs by a hot electron tunneling mechanism, while crosslinks form via a self-stimulating growth mechanism.
