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.
手性螺旋芳烃是一个完全共轭的体系，没有手性碳原子，但它可以在室温下有效地过滤自旋，这是手性诱导自旋选择性效应的结果。手性决定了通过螺旋芳烃传递的电子的自旋，并且基于这些分子的磁阻器件在 H 图上显示出反对称磁阻。
