Molecular spins provide potential building units for future quantum information science and spintronic technologies. In particular, doublet (S = ¹/₂) and triplet (S = 1) molecular spin states have the potential for excellent optical and spin properties for these applications if useful photon-spin mechanisms at room temperature can be devised. Here we explore the potential of exploiting reversible energy transfer between triplet and doublet states to establish magnetosensitive luminescence and spin polarization. We investigate the dependence of the photon-spin mechanism on the magnitude and sign of the exchange interaction between the doublet and triplet spin components in amorphous and crystalline model systems. The design of a magnetic field inclination sensor is proposed from understanding the required “structure” (spin interactions) to “function” (magnetosensitivity).

可逆能量转移产生的自由基自旋极化和磁敏性

分子自旋为未来的量子信息科学和自旋电子技术提供了潜在的构建单元。特别是，如果可以设计出室温下有用的光子自旋机制，那么双重态（ S = ¹ / ₂）和三重态（S = 1）分子自旋态对于这些应用具有优异的光学和自旋特性的潜力。在这里，我们探索利用三重态和双重态之间的可逆能量转移来建立磁敏发光和自旋极化的潜力。我们研究了光子自旋机制对非晶和晶体模型系统中双重态和三重态自旋分量之间交换相互作用的大小和符号的依赖性。磁场倾角传感器的设计是从理解所需的“结构”（自旋相互作用）到“功能”（磁敏性）提出的。
