This work explores the idea of charge transfer from a metal surface to an organic moiety with an interrupted aromatic framework, resulting in aromatization of the latter.  This charge transfer creates an organic monolayer which behaves metallically for all practical purposes (i.e., bandgap is much smaller than before).
