There has been a very rapid development of original systems that can be remotely controlled or addressed by playing with chemical and physical concepts. Here, we present the synergetic combination of external magnetic and electric fields to promote, in a double contactless mode, the rotational motion and the concomitant generation of light emission at the level of a gold-coated iron wire. The latter can be moved by rotating magnetic fields. Simultaneously, an electric field induces its remote polarization, which triggers the local generation of electrochemiluminescence (ECL) by bipolar electrochemistry. During rotation, the motion is tracked by changes in ECL intensity as a function of the orientation of the conducting wire in the electric field. The ECL behavior of the rotating bipolar wire is rationalized by considering the angular dependence of the polarization. Unlike previously reported systems, the rotation induces enhanced ECL emission due to the convective flow produced by the motion. This demonstrates that ECL emission can be coupled to magnetically controlled rotating bipolar objects. Such dual magnetically and electrically addressable dynamic systems open exciting prospects for integrating new functions such as imaging and sensing capabilities.

通过双极电化学发光跟踪磁性旋转物体

原始系统的发展非常迅速，可以通过玩弄化学和物理概念来对其进行远程控制或解决。在这里，我们提出了外部磁场和电场的协同组合，以双非接触模式促进了旋转运动以及伴随着镀金铁丝水平的发光的产生。后者可以通过旋转磁场来移动。同时，电场会感应其远距离极化，从而通过双极电化学触发局部电化学发光（ECL）的产生。在旋转期间，通过ECL强度的变化来跟踪运动，该变化是导线在电场中的方向的函数。通过考虑极化的角度依赖性，可以合理化旋转双极导线的ECL行为。与以前报道的系统不同，由于运动产生的对流，旋转引起增强的ECL排放。这表明ECL发射可以耦合到磁控旋转双极性物体。这样的磁和电可寻址双动力系统为集成诸如成像和传感功能之类的新功能开辟了令人兴奋的前景。
