Most information processing devices, including state of the art microchips, rely on the movement of charge. However, electrons as well as possessing charge also have the quantum mechanical property called spin, which is responsible for magnetic phenomena, for example. Devices which rely on the movement of spin to perform their function are known as magnetoelectronic or spintronic devices. Spintronic applications could include ultra-fast switches or combined logic / storage devices.Recent theoretical studies predict that organic molecules would make excellent components for spintronic devices (Rocha et al., Nature Materials, 2005). Therefore, to measure the spin transport properties of organic molecules is an extremely important goal. We have recently shown that a high resolution probe microscope (a scanning tunnelling microscope or 'STM') can be used to measure the electrical properties of single molecules in a wide variety of environments, including solutions. We propose to adapt these methods to measure the spintronic properties of organic molecular wires down to the single molecule level for the first time. This will contribute to the scientific understanding of how spin is transported through molecules.

大多数信息处理设备，包括最先进的微芯片，都依赖于电荷的运动。然而，除了拥有电荷外，电子还具有称为自旋的量子力学性质，例如，自旋是产生磁现象的原因。依靠自旋运动来执行其功能的器件称为磁电子器件或自旋电子器件。自旋电子学的应用可能包括超快开关或组合逻辑/存储设备。最近的理论研究预测，有机分子将成为自旋电子学设备的优秀组件(Rocha等人，自然材料，2005年)。因此，测量有机分子的自旋输运性质是一个极其重要的目标。我们最近已经证明，高分辨率探针显微镜(扫描隧道显微镜或‘STM’)可以用于在包括溶液在内的各种环境中测量单分子的电学性质。我们建议首次采用这些方法来测量有机分子导线的自旋电子学性质，并将其细化到单分子水平。这将有助于科学地理解自旋是如何通过分子传输的。
