On‐Surface Polymerization of Bis(pyridyl)butadiyne Evidenced by Scanning Tuneling Microscopy and Application in Photocatalysis

Small Structures, Volume 7, Issue 3, March 2026.
This work reveals direct on‐surface photosynthesis of Poly‐bis(pyridyl)butadiyne (PBPyB) from simple BPyB precursors. Long straight 1D‐conjugated polymer wires with trans positioning of the pyridine moieties are revealed for the first time by scanning tunneling microscopy (STM).
