Metal-Free on-Surface Photochemical Homocoupling of Terminal Alkynes
The reaction occurred with high efficiency and selectivity within a self-assembled monolayer (SAM) of aryl-alkynes and led to the generation of large domains of ordered butadiynyl derivatives.

Role of the Substrate Orientation in the Photoinduced Electron Dynamics at the Porphyrin/Ag Interface
By time-resolved two-photon photoemission measurements, we track the relaxation processes of the first two excited molecular states at the interface between porphyrin, the essential chromophore in chlorophyll, and two different orientations of the silver surface.
