In article number 1900318, Kuijuan Jin, Gui Yu, and co‐workers report the fabrication and study of diketopyrrolopyrrole‐based polymer organic spin‐valves. The spinterface of this polymer with Co and Ni80Fe20 electrodes shows distinct magnetoresistance (MR) values. The effect of the alkyl side chain lengths in the polymer backbones on the behavior of the spin valves is also investigated. In addition, MR ratios of 30% can be reached. These results indicate that this series of polymers has potential for use in future organic spintronics.
