Chiral helicene , a fully conjugated system without stereogenic carbon, can filter spins effectively at room temperature, a consequence of the chiral‐induced spin‐selectivity effect. The chirality dictates the spin of the electrons transferred through helicene, and magnetoresistance devices based on these molecules show antisymmetric magnetoresistance versus H plots.
