Cationic chiral helicenes, fully conjugated systems without stereogenic carbons, 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 the helicene framework and magnetoresistance devices based on these molecules show antisymmetric magnetoresistance versus H plots.
