A ligand oxidation structure-adaptive strategy for copper passivation.

ABSTRACT: Despite enormous efforts, copper corrosion remains a key inducement causing huge economic losses in electrical, construction, and military industries, and deteriorates the performance of semiconductor devices. Here we show that a set of ligands functionalized with both catechol and aromatic amine groups achieves environmentally-adaptive copper passivation and fully preserves the intrinsic electrical and thermal conductivities of copper and its alloys. The oxidation of ligands in corrosive environments causes the structure-adaptation of the passivation layer, further enhancing the corrosion resistance to harsh environments including alkali and salt solutions, thermal treatment, and UV-light- and oxygen-enriched conditions. Simply adsorbing these ligands on the surface of copper, brass, copp
