Click it: The applicability of a formal [2+2] cycloaddition between electron-rich alkynes and electron-deficient TCNQ on an atomically clean Au(111) surface was demonstrated by scanning tunneling microscopy (STM) and X-ray photoelectron spectroscopy (XPS). At low coverage, monomeric and self-assembled dimeric species of the initial compounds as well as of the reaction product, a TCNQ-conjugated porphyrin, could be visualized.
