Abstract: A composition of matter for a polymeric material for magnetic coupling through strong hydrogen bonds. A hydrogen bound structural directing entity, such as the bifluoride ion, HF2?, or coordination polymers incorporating strong OH...F type interactions can be used to manufacture organic polymers which allow, via strong hydrogen bonds, the bridging across polymeric magnetic layers to couple spin-polarized electrons to the conduction band, in order to enable control of the electron spin state for spintronic applications.
