The present invention relates to an electronic device comprising a printed substrate comprising a trace of molecular ink thereon, the molecular ink being sintered to form a conductive metal trace forming the electronic device, wherein the molecular ink is chosen from a) a flake-less printable composition of 30-60 wt % of a C8-C12 silver carboxylate, 0.1-10 wt % of a polymeric binder and balance of at least one organic solvent, all weights based on total weight of the composition; or b) a flake-less printable composition of 5-75 wt % of bis(2-ethyl-1-hexylamine) copper (II) formate, bis(octylamine) copper (II) formate or tris(octylamine) copper (II) formate, 0.25-10 wt % of a polymeric binder and balance of at least one organic solvent, all weights based on total weight of the composition.
