Summary: The design of organometallic complexes is crucial in modern organic chemistry and catalysis. On-surface synthesis has recently emerged as a disruptive method to design compounds and nanomaterials previously considered impossible. The activation of inner diacetylene moieties of a molecular precursor by copper surface adatoms has led to the formation of unprecedented organocopper metallacycles on Cu(111), paving the way for new avenues in organometallic compound engineering and polyyne chemistry on surfaces.

Summary: Copper-catalyzed alkyne azide click chemistry (CuAAC) is important for drug development and biological materials labeling. A new tridentate Cu-ligand called TDETA was synthesized as a scalable and non-toxic alternative to HN3 and the previously used DTEA ligand. TDETA showed excellent solubility in organic solvents and aqueous solutions, outcompeted commercial ligands THPTA and TBTA for various azide and alkyne combinations using Cu(I) and Cu(II) species, and had a 80% recovery yield.

Summary: Supramolecular electronics use noncovalent interactions like π-π and hydrogen bonding to introduce molecular assemblies into electronic devices. This research demonstrates a strategy for building electronically robust switches using two different noncovalent interactions. By compressing the junction, the single-supermolecule switch is turned ON through π-π interactions dominating the transport. Stretching the junction to form hydrogen-bonded dimers turns the switch OFF, resulting in a dramatic decrease in conductance. The study shows the potential for designing robust bistable mechanoresponsive devices for integrated circuits in microelectromechanical systems.
