摘要： An electrochemical cell, and an associated process, wherein the cell includes a controlled electrode surface comprising an electrode with a metallic current collector having a surface, an electrolyte and a reduced additive. The invention further includes a passivating layer at the interface between the metallic current collector and the electrolyte. The passivating layer includes the reduced additive. This passivating layer substantially precludes contact between electrolyte solvent and surface of the metallic current collector to, in turn, substantially prevent gas formation within the cell, which would otherwise result from decomposition of the solvent upon contact with the surface of the metallic current collector. Also, the reduced additive will likewise be substantially precluded from generating a gas upon its decomposition.

摘要： Electroluminescent devices have, as the active layer, a polymer having a chain comprising a plurality of electroluminescent groupings, adjacent pairs of the electroluminescent groupings being connected via two benzene rings linked by only a single covalent bond, at least one of the benzene rings bearing, at a position ortho to the covalent bond, a substituent of sufficient size that the two benzene rings are essentially not conjugated with each other. Preferred electroluminescent groupings comprise a chain of three or more para-phenylene groups connected to one another by amide, carboxy, ester, urea, urethane or vinyl groups. The polymers have a fixed conjugation length with predictable electroluminescent properties.
