"individual metal ions are anchored to center of porphyrin molecules' organic ring, by baking at several hundred °C under ultra-high vacuum while sitting on gold surface, forming nm-long chains... then these porphyrin molecules docked along edges of graphene ribbon backbone at regular intervals alternating between ribbon's left/ right sides... spin-carrying electrons in metal center stay localized on metal atom/ corresponding electrons in graphene ribbon spread out along both edges... electrical/ magnetic conductor"
