| Research Abstract |
To select a certain electronic arrangement among several possible states is a powerful tool to tune the molecular responses such as magnetic or optical ones. Moreover, those electron arrangements can attribute to the each molecules, which means the information can be divided into the individual molecules. Our study aims to create a mechanic approach to arrange an electron within a multi-centered redox system.
We chose the simplest continuous mechanics, a rotation at the fixed position within a Cu(II/I) coordination structure. The coordination environment provides twofold advantages, i)the rotational motion induces the coordination structural change, which significantly affects the redox potential of the metal center, ii) The coordination-bond formation through a rotation trail makes a double-minimum potential, enable us to trap a two different electronic states with enough thermal stability. Based on this basic structure, we evaluated the conversion rate of rotation isomer, and demonstrated the synchronization of rotation and electromotive force, intramolecular electron transfer triggered with rotational motion, and photoinduced rotation.
