Micro-OptoMechanical运动与SoftOxometalates（SOMs）：利用奇异光势控制单个软草酸豌豆荚的运动
Micro-OptoMechanical Movements (MOMs) with SoftOxometalates (SOMs): Controlled Motion of Single Soft-Oxometalate Pea-pods Using Exotic Optical Potentials
摘要：
材料设计和合成领域的一个重要挑战是从定义明确的前体开始故意设计介观物体，并在其中诱导定向运动以模拟生物过程。最近，介观的金属氧化物为基础的软氧代金属（SOMs）已被合成从定义明确的分子前体超越政权的平移周期性。在这里，我们表明，它实际上是可以控制地移动这样一个不对称的SOM的形状的一个“豌豆荚”沿复杂的路径使用定制的复杂的光学势所产生的自旋轨道相互作用，由于一个紧密聚焦的线性偏振高斯光束传播通过分层介质中的光阱。我们证明了运动的个人被困SOM沿圆形路径超过15 $μ$ m在一个完美的控制方式，通过简单地改变输入偏振的捕获激光。这种受控运动可以具有从催化到动态介观结构的构建的广泛应用。
英文摘要：
An important challenge in the field of materials design and synthesis is to deliberately design mesoscopic objects starting from well-defined precursors and inducing directed movements in them to emulate biological processes. Recently, mesoscopic metal-oxide based Soft Oxo Metalates (SOMs) have been synthesized from well-defined molecular precursors transcending the regime of translational periodicity. Here we show that it is actually possible to controllably move such an asymmetric SOM-with the shape of a `pea-pod' along complex paths using tailor-made sophisticated optical potentials created by spin-orbit interaction due to a tightly focused linearly polarized Gaussian beam propagating through stratified media in an optical trap. We demonstrate motion of individual trapped SOMs along circular paths of more than 15 $μ$m in a perfectly controlled manner by simply varying the input polarization of the trapping laser. Such controlled motion can have a wide range of application starting from catalysis to the construction of dynamic mesoscopic architectures.
