To resolve the molecular structure and electron transport mechanism responsible for centimeter-scale electrical conductivity in cable bacteria.
Characterized the molecular composition and coordination geometry of the conductive periplasmic fibers spanning centimeter-long cable bacteria filaments.
Evaluated the supramolecular packing and ligand-metal interactions facilitating long-range electron delocalization.
Revealed that conductive fibers embed an extended nickel-organic framework comprising bundled, intertwined nanoribbons.
Showed that repeat units feature multiple nickel centers bridged by organic dithiolene ligands, establishing extensive conjugation and electron delocalization for macroscale conductance.
