近年来，磁场在手性化学体系中的应用取得了丰硕的成果。在1986年的一篇前瞻性论文《手性金属？》中，沃利斯、卡雷尔和杰克D. Dunitzforecast“手性导体中对适当对称元素的限制可能与新特性的出现有关，这些特性与施加的电场和磁场及其内部对应物之间的相互作用有关。这是一个有先见之明的评论，但它已经变得明显的方式，不会被预见到的细节，由作者。本文综述了Dunitzand的同事基于对映体纯四硫富瓦烯衍生物的手性导体的发展，这些衍生物将空间群限制在只有第一类对称操作的空间群，以及当磁场施加到手性晶体等系统中时，与电子传输相关的新出现的性质。这些包括电磁手征各向异性（eMChA）、逆电磁手征各向异性（ieMChA）、螺旋磁化和手性诱导的自旋选择性（CISS）。讨论非手性TTF晶体成为手性晶体的情况的结论似乎只是引入了一个矛盾修饰法。
Recently, the application of magnetic fields to chiral chemical systems has been rewarding. In a forward‐looking 1986 paper, ‘Chiral Metals?’,Wallis,Karrer, andJack D. Dunitzforecast ‘that the limitation to proper symmetry elements in a chiral conductor could be associated with the emergence of new properties, those connected with interactions between applied electric and magnetic fields and their internal counterparts.’ This was a prescient remark, but it has become manifest in ways that would not have been foreseen in its details by the authors. Here are reviewed the development of chiral conductors broadly imagined byDunitzand coworkers, based on enantiopure tetrathiafulvalene derivatives that restrict space groups to those that have only symmetry operations of the first kind, as well as the new emergent properties associated with the transport of electrons when magnetic fields are applied to chiral crystals among other systems. These include electrical magnetochiral anisotropy (eMChA), inverse electrical magnetochiral anisotropy (ieMChA), helimagnetism and chirality induced spin selectivity (CISS). The conclusion discussing the circumstances under which achiral TTF crystals becomes chiral, only seems to introduce an oxymoron.
